| 1 | Selective removal of 2,4-dichlorophenoxyacetic acid from water by molecularly-imprinted amino-functionalized silica gel sorbent显示文摘A molecularly-imprinted amino-functionalized sorbent for selective removal of 2,4-dichlorophenoxyacetic acid(2,4-D) was prepared by a surface imprinting technique in combination with a sol-gel process.The 2,4-D-imprinted amino-functionalized silica sorbent was characterized by FT-IR,nitrogen adsorption and static adsorption experiments.The selectivity of the sorbent was investigated by a batch competitive binding experiment using an aqueous 2,4-D and 2,4-dichlorophenol(2,4-DCP) mixture or using an aqueous 2,4-D and 2,4dichlorophenylacetic acid(DPAC) mixture.The largest selectivity coefficient for 2,4-D in the presence of 2,4-DCP was found to be over 18,the largest relative selectivity coefficient between 2,4-D and 2,4-DCP over 9.The static uptake capacity and selectivity coefficient of the 2,4-D-imprinted functionalized sorbent are higher than those of the non-imprinted sorbent.The imprinted functionalized silica gel sorbent offered a fast kinetics for the extraction/stripping of 2,4-D,73% of binding capacity(200 mg/L 2,4-D onto 20 mg of imprinted sorbent) was obtained within 5 min and the adsorbed 2,4-D can be easily stripped by the mixture solution of ethanol and 6 mol/L HCl(V:V =1:1).In a test of five extraction/stripping cycles,the adsorption capacity of the sorbent was all above 93% of that of the fresh sorbent.Experimental result showed the potential of molecularly-imprinted amino-functionalized sorbent for selective removal of 2,4-D. | Deman Han ,Wenping Jia,Huading Liang Department of Chemistry,Taizhou University,Linhai 317000,China. | 2010 | Journal of Environmental Sciences2010，22，2： | 11 |
| 2 | Pd/C modified with Sn catalyst for liquid-phase selective hydrogenation of maleic anhydride to gamma-butyrolactone显示文摘Pd catalysts suffered from poor selectivity and stability for liquid-phase hydrogenation of maleic anhydride(MA) to gamma-butyrolactone(GBL).Thus,Pd/C catalysts modified with different Sn loadings were synthesized,and characterized by XRD,XPS,TEM and elemental mapping.The types of alloy phase and the amounts of the surface Pd-SnOx sites altered along with Sn/Pd mass ratios from 0-1.0synthesized in the process of preparation.The maximum reaction rate was 0.57 mol-GBL/(mol-Pd min)and selectivity was 95.94%when the Sn/Pd mass ratio was 0.6.It might be attributed to the formation of Pd_2Sn alloy and less amounts of Pd-SnOx sites. | Rongrong Li Jia Zhao Deman Han Xiaonian Li | 2017 | Chinese Chemical Letters2017，28，6： | 5 |
