In this paper two newly developed hypercrosslinked resins were used to treat micropolluted drinking water and their static and kinetic adsorption were investigated at 293 K. The results show that these two adsorbents are superior to Amberlite XAD-4 for removing chloroform and trichloroethylene in aqueous solutions. The breakthrough capacity and the total capacities from mini-column adsorption studies for chloroform and trichloroethylene on XAD-4, ZH-01 and ZH-00 are calculated respectively under experimental conditions 相似文献

本文用邻苯二酚经过先桥接后偶联,用愈创木酚,水杨醛经过先偶联后桥接的方法,合成了三类双偶氮开链冠醚1,2和3.方法简便,产率较高,借助于可见光谱测定,考查了它们在溶液中与碱金属和碱士金属盐等的配位性能.结果表明,1在95:5四氢呋喃-水(v/v)中,对高氯酸锂和高氯酸钙有良好的选择性变色作用.本文对变色作用的反应机理进行了详细的讨论.可以认为,变色作用的产物是分子内配盐,这已由1与高氯酸钙制成的配合物的元素分析,可见光谱和红外光谱的测定所证明. 相似文献
