| 1 | Synthesis of novel nanomaterials and their application in efficient removal of radionuclides显示文摘With the development of nuclear energy, large amounts of radionuclides are inevitably released into the natural environment. It is necessary to eliminate radionuclides from wastewater for the protection of environment. Nanomaterials have been considered as the potential candidates for the effective and selective removal of radionuclides from aqueous solutions under complicated conditions because of their high specific surface area, large amounts of binding sites, abundant functional groups, pore-size controllable and easily surface modification. This review mainly summarized the recent studies for the synthesis, fabrication and surface modification of novel nanomaterials and their applications in the efficient elimination and solidification of radionuclides,and discussed the interaction mechanisms from batch experiments, spectroscopy analysis and theoretical calculations. The sorption capacities with other materials, advantages and disadvantages of different nanomaterials are compared, and at last the perspective of the novel nanomaterials is summarized. | Xiangxue Wang Long Chen Lin Wang Qiaohui Fan Duoqiang Pan Jiaxing Li Fangting Chi Yi Xie Shujun Yu Chengliang Xiao Feng Luo Jun Wang Xiaolin Wang Changlun Chen Wangsuo Wu Weiqun Shi Shuao Wang Xiangke Wang | 2019 | Science China Chemistry2019，62，8： | 20 |
| 2 | Modeling of radionickel sorption on MX-80 bentonite as a function of pH and ionic strength显示文摘MX-80 bentonite was detected using acid-based titration, XRD and FTIR in detail. The sorption behavior of 63Ni(Ⅱ) from aqueous solution to MX-80 bentonite was investigated as a function of solid content, ionic strength and pH by using batch technique. The experimental data of 63Ni(Ⅱ) sorption on MX-80 bentonite was obtained using the diffuse layer model (DLM) with the aid of FITEQL 3.1 program. The results indicated that the sorption of 63Ni(Ⅱ) on MX-80 bentonite was mainly dominated by surface complexation, and cation exchange also contributed partly to 63Ni(Ⅱ) sorption at low pH values. The sorption isotherms were simulated by Langmuir and Freundlich models, and the results indicated that Freundlich isotherm model fitted the sorption data better than the Langmuir isotherm model. The results are crucial to evaluate the sorption and migration of radionickel in MX-80 bentonite. | SHAO DaDong XU Di WANG SuoWei FANG QiaoHui WU WangSuo DONG YunHui WANG XiangKe | 2009 | Science China Chemistry2009，52，3： | 13 |
| 3 | Sorption of uranyl ions on TiO_2:Effects of pH,contact time,ionic strength,temperature and HA显示文摘Sorption of U(VI) onto TiO_2 as functions of pH, ionic strength, contact time, soil humic acid(SHA), solid-to-liquid ratio and temperature was studied under ambient conditions using batch and spectroscopic approaches. The sorption of U(VI) on TiO_2 was significantly dependent on pH and ionic strength. The presence of SHA slightly enhanced the sorption of U(VI) on TiO_2 below pH 4.0, while it inhibited U(VI) sorption in the higher pH range. U(VI)sorption on TiO_2 was favored at high temperatures, and the sorption process was estimated to be endothermic and spontaneous. Reduction of U(VI) to lower valent species was confirmed by X-ray photo-electron spectroscopy analysis. It is very interesting to find that U(VI) sorption on TiO_2 was promoted in solutions with higher back-ground electrolyte concentrations. In the presence of U(VI), higher back-ground electrolyte made more TiO_2 particles aggregate through(001) facets, leading more(101) facets to be exposed. Therefore, the reduction of U(VI) was enhanced by the exposed(101) facets and more U(VI) removal was observed. | Jingjing Wang Bihong He Xiaoyan Wei Ping Li Jianjun Liang Shirong Qiang Qiaohui Fan Wangsuo Wu | 2019 | Journal of Environmental Sciences2019，31，1： | 7 |
| 4 | Value of section plane,MPR,and 3D-CTVR techniques in the fine differential diagnosis of ossicular chain in the case of conductive hearing loss with intact tympanic membrane显示文摘Aim: To assess the quality of high-resolution CT section planes(HRCT), multi-planar reformation(MPR) and 3-dimensional volume rendered computer tomography(3D-CTVR) were here used in the fine differential diagnosis of ossicular chain in the case of conductive hearing loss with intact tympanic membrane.Methods: Here, 17 cases of otosclerosis and 22 cases of ossicular chain deformity were selected. All patients had normal external ear canals,intact tympanic membranes, conductive hearing loss, type A tympanograms, and negative Gelle's tests. The respective radiological reports of the status of the ossicles via 3 protocols were compared to surgical findings. The quantitative assessments of the representation of different segments of the ossicular chain were based on a 3-point scoring system.Results: MPR and CTVR imaging both showed the integrity of whole ossicular chain well. MPR and CTVR imaging were found to be superior to section planes with respect to showing the superstructure of the stapes and malformations(P > 0.05).Conclusion: CTVR and MPR imaging were found to be better able to show the whole ossicular chain in the conductive hearing loss with normal tympanic membranes. Furthermore, the use of these techniques can have profound contributive value in the differential diagnosis of otosclerosis and ossicular chain absence or malformation. | Yang Liu Feng Yang QiaoHui Lu Danheng Zhao | 2017 | Journal of Otology2017，12，2： | 7 |
| 5 | The sorption mechanisms of Th(Ⅳ) on attapulgite显示文摘The surface properties of intrinsic and activated attapulgite were studied using potentiometric titration.The sorption mechanisms of Th(IV) on intrinsic and activated attapulgite were investigated by employing surface complexation model and FITEQL 3.2 code.The results indicated that the sorption sites of intrinsic attapulgite involved in the sorption process were main ion exchange site(≡ XNa/K),strong site(≡ SsOH) and weak site(≡ SwOH),while only strong site(≡ SsOH) and weak site(≡ SwOH) were predominant for activated attapulgite.At pH < 2.5,the species of Th(IV) was main Th4+ in aqueous solution;then the hydrolysis species of Th(IV)(i.e.,Th(OH)22+,Th(OH)+3 and Th(OH)04) gradually formed as pH increasing.For the sorption of Th(IV) on intrinsic attapulgite,both ion exchange species(≡ X2Th) and inner-sphere surface complexes(≡ SsOTh) were dominant,while only inner-sphere surface complexes(i.e.,≡ SsOThOH and ≡ SwOTh) were observed for Th(IV) sorption to activated attapulgite.In the presence of humic acid(HA),the sorption of Th(IV) on activated attapulgite was obviously enhanced;and both ≡ SsOH-HA-Th and ≡ SsOTh were the predominant speciation.It was also interesting to find that the addition of HA obviously provoked the desorption behavior of Th(IV). | PAN DuoQiang FAN QiaoHui DING KeFei LI Ping LU Yan YU Tao XU Jiang WU WangSuo | 2011 | Science China Chemistry2011，54，7： | 6 |
