| 摘 要： | 壳聚糖可溶于酸性介质中并发生降解［１］，因此，利用壳聚糖制备螯合树脂时，需进行改性，使之转变为不溶不熔的交联型树脂．但交联后的壳聚糖虽不溶于酸，其吸附能力却比交联前明显降低［２］．模板合成法是制备具有一定“记忆”功能的高分子吸附螯合树脂的一种新方法，...

| Abstract: | Using Cu() as template and ethylene glycol bisglycidyl ether as crosslinking agent, a novel adsorption resin of chitosan condensed with salicylaldehyde has been synthesized. Its static adsorption capacity, kinetic and isothermal curves for Cu() have been obtained. The adsorption capacity of the resin for Cu() was 177.78 mg/g and selectivity coefficient KCu()/Fe() was 46, both much greater than that of resin without being treated by template. The resin cna be reused after simple regeneration. |
