| 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 | 薄壁钢管混凝土短柱在局部轴压下的性能研究显示文摘对轴向局部压力作用下的薄壁钢管混凝土(STCC)短柱进行受力性能的试验分析,共测试了46个试验构件,其中有36个STCC构件和10个素混凝土构件。主要参数有:1)截面类型:圆形和方形;2)局部受压面积比(混凝土横截面面积与局部受压面积之比):1~25;3)钢管宽度(或直径)与壁厚的比率,B(或D)/t:52.1~104.7。结果发现,复合截面的弯曲极限强度会随局部受压面积比的增加而减小;对钢管核心区混凝土的约束作用和局部加载STCC构件的极限强度会随着钢管宽度(或直径)与厚度之比值的增加而减小。分析同时发现,在局部轴压作用下,一般圆形钢管比方形管能更好地约束核心混凝土。 | Linhai Han, Wei Liu and Youfu Yang | 2008 | 钢结构2008，23，9： | 6 |
