| 1 | Gangba sheep in the Tibetan plateau:Validating their unique meat quality and grazing factor analysis显示文摘Gangba sheep are known for having typical sensory characteristics attributed to free range conditions and grazing on wild plants.The genuine Gangba mutton was selected as the experimental group,and the commercial Tibetan mutton was selected as the control group,the nutritive composition of basic chemical components,amino acids and fatty acids in mutton were investigated to correlate its unique meat quality and eating satisfaction.The results showed that fatty acids were significantly higher(P<0.05)in Gangba mutton than in commercial mutton,and the higher content of flavoring amino acids(glutamic acid and aspartame)were primarily responsible for the taste attributes umami of meat juices.Moreover,the trace elements analysis in mutton and grazing factors(forage,water source and soil)were conducted,to explain the source of essential trace elements in mutton.The concentrations of essential trace elements show that the Gangba mutton was a valuable source for highly available Cu and Zn in human nutrition,and well managed with few detected of toxicity metal.The concentrations of essential trace elements in mutton are closely related to the trace elements in environmental grazing factors.In conclusion,the congenital grazing conditions(a highly mineralized water resource,natural forages and clean soils)were shown to contribute to the unique meat characteristics of Gangba sheep. | Qiangying Zhang Ming Que Wei Li Shuang Gao Xin Tan Duo Bu | 2021 | Journal of Environmental Sciences2021，33，3： | 8 |
| 2 | Preparation,Characterization and Application of Mesoporous Carbon Materials Derived from MgO Template for Removal of Heavy Metals显示文摘Mesoporous carbon adsorbents were prepared for the adsorption of Cu(Ⅱ)and Pb(Ⅱ)by calcination with gelatin,chitosan and sucrose as carbon precursor respectively,and magnesium citrate as MgO template precursor under high temperature argon atmosphere.The effects of the mass ratio of carbon precursor/magnesium citrate and calcination temperature on the adsorption performance of Cu(Ⅱ)and Pb(Ⅱ)ions were investigated.The results showed that the optimum preparation process of adsorbent was obtained as follows:gelatin was carbon precursor,and gelatin and magnesium citrate were calcined at a mass ratio of 5∶5 under argon atmosphere of 600℃for 2 h.The adsorbent exhibited mesostructure with a pore size of about 5.1 nm and a high specific surface area of 783 m^2/g.The as-synthesized adsorbent exhibited high adsorption capacity for Cu(Ⅱ)(8.3 mg/g)and Pb(Ⅱ)(28 mg/g). | Qiangying ZHANG Ruizhi WANG Jian LIU Jinhui WU Lu XIA Xiao CUI Duo BU Shuang GAO | 2020 | Meteorological and Environmental Research2020，11，1： | 0 |
| 3 | Effectively arsenic(Ⅴ)and fluoride removal in geothermal water using magnetic Fe_(3)O_(4)@MgO nanoparticles显示文摘High residual concentration of arsenic and fluoride is a tricky problem to be solved in the process of reinjection after geothermal water utilization.We develop a method to simultaneously remove As(V)and F-from geothermal water using magnetic Fe_(3)O_(4)@MgO adsorbent,fabricated via a one-step method.The effects of pH,contact time,adsorbent dose and temperature on the removal efficiency were investigated systematically.The results show that the Fe_(3)O_(4)@MgO composite has a wide range of pH(2-11),ultrafast removal dynamics(As(V):2 min;F-:30 min),and high removal efficiency(As(V):99.9%;F-:96.6%).The adsorption kinetics follows the pseudo-secondorder kinetics model,and the adsorption isotherm model fits Freundlich.The adsorption capacity of As(V)and F-can reach 123 and 98.4 mg/g,respectively.The exchange of As(V)and F-with Mg-hydroxyl groups hydrolysis by MgO was determined the adsorption mechanism.The Fe_(3)O_(4)@MgO adsorbent was capable of achieving the adsorption efficiency as high as 99.9%for As(V)and 97.3%for F-in real geothermal water,respectively.Hence,the proposed Fe_(3)O_(4)@MgO composite exhibited as an excellent adsorbent for the remediation of As-and F-contaminated geothermal water. | Qiangying Zhang Xin Tan Tao Yu | 2023 | Chinese Chemical Letters2023，34，5： | 0 |
