中文摘要：

以乙二醇单苯醚、甲醛为原料,采用分散聚合方法制备出乙二醇单苯醚-甲醛聚合物微球;经二甲亚砜氧化,制得醛基化改性微球（PB-CHO）;微球（PB-CHO）与三乙烯四胺进行Schiff碱反应及加氢反应,制备出球型乙二醇单苯醚-甲醛负载三乙烯四胺螯合树脂（PB-TETA）。对所制备的新型螯合树脂进行了红外光谱、扫描电镜等表征,并研究了PB-TETA对Cu^2＋的吸附性能。结果表明,在pH值为5时,PB-TETA对Cu^2＋的最大吸附量为0.16mmol/g;树脂对Cu^2＋的吸附受液膜扩散控制;吸附动力学符合拟一级动力学模型;等温吸附符合Langmuir吸附模型。

英文摘要：

A new kind of chelating resin based on ethyleneglycol monophenylether- formaldehyde polymeric beads containing triethylene tetramine （PB-TETA） was synthesized. Its structure was characterized by Fourier transform-infrared spectra （FT-IR） and scanning electron microscopy （SEM）. The adsorption capacities of the resin for Cu^2＋, Pb^2＋, Ag＋, Hg^2＋, Co^2＋, Zn^2＋, and Ni^2＋ were investigated. Specially, the adsorption kinetic and adsorption isotherm of the resin for Cu^2＋ were also studied in details. The results showed that the resins had the highest affinity to Cu^2＋ among metal ions above at pH=5. The maximum adsorption capacity was 0.16mmol/g. The kinetics data indicated that the adsorption process were governed by the film diffusion and followed pseudo-first-order rate model for PB-TETA. The isotherm adsorption results indicated that the adsorption of Cu^2＋ on PB-TETA fitted better with the Langmuir model.
