| 1 | Reuse of Fenton sludge as an iron source for NiFe_2O_4 synthesis and its application in the Fenton-based process显示文摘The potentially hazardous iron-containing sludge from the Fenton process requires proper treatment and disposal, which often results in high treatment cost. In this study, a novel method for the reuse of Fenton sludge as an iron source for the synthesis of nickel ferrite particles(NiFe_2O_4) is proposed. Through a co-precipitation method followed by sintering at 800°C, magnetic NiFe_2O_4 particles were successfully synthesized, which was confirmed by powder X-ray diffraction(XRD), scanning electronic microscopy(SEM), energy dispersive spectroscopy(EDS), Fourier transform infrared spectroscopy(FT-IR) and Raman spectroscopy. The synthesized NiFe_2O_4 could be used as an efficient catalyst in the heterogeneous Fenton process. In phenol degradation with H_2O_2 or NiFe_2O_4 alone, the phenol removal efficiencies within the reaction time of 330 min were as low as 5.9% ± 0.1% and 13.5% ±0.4%, respectively. However, in the presence of both NiFe_2O_4 and H_2O_2, phenol removal efficiency as high as 95% ± 3.4% could be achieved, indicating the excellent catalytic performance of NiFe_2O_4 in the heterogeneous Fenton process. Notably, a rapid electron exchange between_Ni II and_Fe III ions in the NiFe_2O_4 structure could be beneficial for the Fenton reaction. In addition, the magnetic catalyst was relatively stable, highly active and recoverable, and has potential applications in the Fenton process for organic pollutant removal. | Hui Zhang Jianguo Liu Changjin Ou Faheem Jinyou Shen Hongxia Yu Zhenhuan Jiao Weiqing Han Xiuyun Sun Jiansheng Li Lianjun Wang | 2017 | Journal of Environmental Sciences2017，29，3： | 10 |
| 2 | Removal of phosphate from wastewater using alkaline residue显示文摘Alkaline residue(AR) was found to be an efficient adsorbent for phosphate removal from wastewater. The kinetic and equilibrium of phosphate removal were investigated to evaluate the performance of modified alkaline residue. After treatment by NaOH(AR-NaOH), removal performance was significantly improved, while removal performance was almost completely lost after treatment by HCl(AR-HCl). The kinetics of the removal process by all adsorbents was well characterized by the pseudo second-order model. The Langmuir model exhibited the best correlation for AR-HCl, while AR was effectively described by Freundlich model. Both models were well fitted to AR-NaOH. The maximum adsorption capacities calculated from Langmuir equation were in following manner: AR-NaOH > AR > AR-HCl. Phosphate removal by alkaline residue was pH dependent process. Mechanisms for phosphate removal mainly involved adsorption and precipitation, varied with equilibrium pH of solution. For AR-HCl, the acid equilibrium pH(< 6.0) was unfavorable for the formation of Ca-P precipitate, with adsorption as the key mechanism for phosphate removal. In contrast, for AR and ARNaOH, precipitation was the dominant mechanism for phosphate removal, due to the incrase on pH(> 8.0) after phosphate removal. The results of both XRD and SEM analysis confirmed CaHPO4·2H2O formation after phosphate removal by AR and AR-NaOH. | Yubo Yan Xiuyun Sun Fangbian Ma Jiansheng Li Jinyou Shen Weiqing Han Xiaodong Liu Lianjun Wang | 2014 | Journal of Environmental Sciences2014，26，5： | 8 |
| 3 | Simultaneous pyridine biodegradation and nitrogen removal in an aerobic granular system显示文摘Simultaneous pyridine biodegradation and nitrogen removal were successfully achieved in a sequencing batch reactor(SBR) based on aerobic granules. In a typical SBR cycle, nitritation occurred obviously after the majority of pyridine was removed, while denitrification occurred at early stage of the cycle when oxygen consumption was aggravated. The effect of several key operation parameters, i.e., air flow rate, influent NH_4^+-N concentration,influent p H and pyridine concentration, on nitritation, pyridine degradation and total nitrogen(TN) removal, was systematically investigated. The results indicated that high air flow rate had a positive effect on both pyridine degradation and nitritation but a negative impact of overhigh air flow rate. With the increase of NH_4^+ dosage, both nitritation and TN removal could be severely inhibited. Slightly alkaline condition, i.e., pH 7.0–8.0, was beneficial for both pyridine degradation and nitritation. High pyridine dosage often resulted in the delay of both pyridine degradation and nitritation. Besides, extracellular polymeric substances production was affected by air flow rate, NH_4^+ dosage, pyridine dosage and p H.In addition, high-throughput sequencing analysis demonstrated that Bdellovibrio and Paracoccus were the dominant species in the aerobic granulation system. Coexistence of pyridine degrader, nitrification related species, denitrification related species, polymeric substances producer and self-aggregation related species was also confirmed by highthroughput sequencing. | Xiaodong Liu Shijing Wu Dejin Zhang Jinyou Shen Weiqing Han Xiuyun Sun Jiansheng Li Lianjun Wang | 2018 | Journal of Environmental Sciences2018，30，5： | 7 |
| 4 | Sensory and chemical assessment of silver pomfret (Pampus argenteus) treated with Ginkgo biloba leaf extract treatment during storage in ice显示文摘This study investigated the physical(L*,a*,b*,texture profile analyses,pH),chemical(TVB-N,K value and TBA),microbiological,amino acid content,and flavor effects that Gingko biloba leaf extract(GBLE)had on silver pomfret(Pampus argenteus)stored at 4±1C in ice for 18 days.Fresh pomfret samples were obtained directly from the local fish market and transported to the laboratory with ice immediately.After being gutted,washed,filleted and trimmed in a water-ice mixture,samples were treated with different concentrations of GBLE(0.0 mg/mL,2.5 mg/mL,5.0 mg/mL,10.0 mg/mL)and packaged in Polyethylene bag,then stored in a refrigerator at 4±1C with ice.The results show that the shelf-life of untreated(0.0 mg/mL)pomfret samples was 8e9 days compared to 14e15 days for the GBLE1(2.5 mg/mL)treated group.The assessment results showed that different concentrations of GBLE had variable effects on preserving the texture parameters of acceptability limit,inhibit lipid oxidation,protein degradation,and microorganism growth.2.5 mg/mL of GBLE was the best for the preservation of pomfret during storage in ice.Therefore,there is potential use for GBLE as a preservative to extend the shelf-life of pomfret during chilled storage in ice. | Weiqing Lan Xu Che Qiaoling Xu Ting Wang Ruoyuan Du Jing Xie Min Hou Han Lei | 2018 | Aquaculture and Fisheries2018，3，1： | 5 |
| 5 | Reductive transformation and detoxification mechanism of 2,4-dinitrochlorobenzene in combined zero valent iron and anaerobic-aerobic process显示文摘A combined zero valent iron (ZVI) and anaerobic-aerobic process was adopted for the treatment of 2,4-dinitrochlorobenzene (DNCB)-containing wastewater. The transformation pathway, reduction of acute toxicity and enhancement of biodegradability were investigated. After pretreatment by ZVI, DNCB in wastewater could be completely converted into 2,4-diaminochlorobenzene (DACB). The ratio of BOD5/COD increased from 0.005±0.001 to 0.168±0.007, while EC 50, 48 hr (V/V) increased from 0.65% to 5.20%, indicating the enhancement of biodegradability and reduction of acute toxicity with the pretreatment by ZVI. DACB was further dechlorinated to m-phenylenediamine during the anaerobic process using methanol as electron donor, with EC50, 48 hr increasing from 5.20% to 48.2%. After the subsequent anaerobic-aerobic process, m-phenylenediamine was degraded completely, with effluent COD of 67.5±10.8 mg/L. This effluent of the subsequent anaerobic-aerobic process was not toxic to zebrafish. The combined ZVI and anaerobic-aerobic process offers bright prospects for the treatment of chlorinated nitroaromatic compound-containing wastewater. | Jinyou Shen Zongyuan Zhou Changjin OU Xiuyun Sun Jiansheng Li Weiqing Han Lin Zhou Lianjun Wang | 2012 | Journal of Environmental Sciences2012，24，11： | 4 |
| 6 | Efficacy and safety of degarelix in patients with prostate cancer:Results from a phase III study in China显示文摘Objective:To establish non-inferiority of gonadotropin-releasing hormone degarelix compared with goserelin in suppressing and maintaining castrate testosterone levels from Day 28 to Day 364 in Chinese patients with prostate cancer.Methods:This is an open-label,multi-centre study in which men aged18 years were randomised in a 1:1 ratio to once-a-month subcutaneous injection of either degarelix(240/80 mg)or goserelin(3.6 mg)for 12 months.The primary endpoint was difference in 1-year cumulative probability of suppressing testosterone to ≤0.5 ng/mL.Non-inferiority was to be established if the lower 95% confidence interval(CI)limit for difference in cumulative probability between the treatment arms was greater than -10%.Secondary endpoints included cumulative probability of prostate-specific-antigen-progression-free-survival(PSA-PFS).Safety was also assessed.Results:Baseline demographics and disease characteristics were similar between degarelix(n=142)and goserelin(n=141)treatment arms.The difference in cumulative probability of maintaining castrate levels from Day 28-364 was 3.6%(95%CI:-1.5%,8.7%),demonstrating non-inferiority of degarelix.The cumulative probability of PSA-PFS at Day 364 was higher for degarelix(82.3%,95%CI:74.7%,87.7%)versus goserelin(71.7%,95%CI:63.2%,78.5%,p=0.038).Adverse events(AEs)were similar between treatment arms,except for more injection site reactions with degarelix versus goserelin.Four(2.8%)and nine(6.4%)patients discontinued due to AEs in degarelix and goserelin groups,respectively. | Yinghao Sun Liping Xie Tao Xu Jorn S.Jakobsen Weiqing Han Per S.Sorensen Xiaofeng Wang | 2020 | Asian Journal of Urology2020，7，3： | 2 |
