| 摘 要： | 用氯乙酰化聚苯乙烯树脂(PS-Acyl-Cl)取代常用的原料氯甲基化聚苯乙烯(PS-CH2-Cl)树脂，固载二乙醇胺(DEA)得到一新型的聚苯乙烯二乙醇胺(PS-Acyl-DEA)树脂. 用这种PS-Acyl-DEA树脂对铜离子进行吸附，并研究了其吸附动力学和吸附等温线. 结果发现，树脂对铜离子的吸附量随DEA担载量的增加而增加，对铜离子的最大吸附量可达3.79 mmol/g，且在pH 5.6~10.5范围内树脂对铜离子均有稳定的吸附量，树脂的吸附率达到93.8%.

| Abstract: | The new polystyrene diethanolamine resin (PSAcylDEA) was synthesized by the reaction of diethanolamine (DEA) with chloracetylated polystyrene (PSAcylCl) instead of chloromethylated polystyrene (PSCH2Cl) which is commonly used. The adsorption kinetics and isotherms of obtained product for cupric ion were studied. The results showed that the adsorption capacity increased as the increasing loading of the product and was steady in the environment with the pH values between 5.6 and 10.5. The Cu2+ adsorption quantity was 3.79 mmol/g and the adsorption rate of the resin to cupric ions was up to 93.8%. |
