摘要
以三乙烯四胺、环氧氯丙烷和氯乙酸为原料,合成了氨基酸结构的螯合树脂,并研究其对Cu^(2+)、Pb^(2+)、Ni^(2+)、Zn^(2+)的吸附性能。结果表明,该树脂对Cu^(2+)、Pb^(2+)、Ni^(2+)比对Zn^(2+)具有良好的吸附性能,其吸附量可达1.40、1.39、1.20及0.4mol/g。
By using triethylene tetramine, chloroacetic acid, and epichlorohydrin as materials, a kind of chelating resin containing amino acid structure was synthesized and its adsorption properties for Cu2+, Pb2+, Ni2+ and Zn2+ have been studied. The results show that this resin has better adsorption properties for Cu2+, Pb2+, Ni2+ than for Zn2+, their adsorption capacities were 1.40, 1.39, 1.20 and 0.4mol/g resin respectively.
