摘要
通过阳离子聚合、水解、二硫代氨基甲酸盐(DTC)修饰三步反应制得DTC修饰率为75%的线性聚乙烯亚胺基二硫代氨基甲酸盐(DTC-LPe I),以此为原料制备了DTC改性开孔聚氨酯泡沫材料。DTC单元与金属离子摩尔比4︰1,金属离子浓度为50 mg/L条件下,该材料对Cu~(2+)、zn~(2+)和Cd~(2+)去除率分别为83.8%、92.9%和94.7%。金属离子被直接吸附于泡沫材料中,可解决常见DTC类重金属捕集剂采取絮凝方式沉淀重金属离子生成的污泥难以回收的问题。
Dithiocarbamated linear polyethyleneimine(DTC-LPEI) with 75%modification rate was synthesized by cationic polymerization,hydrolysis and dithiocarbamate-modification,which was further used as raw material to synthesize dithiocarbamate-modified open cell polyurethane foam.The removal rates of the foam for Cu~(2+)、Zn~(2+) and Cd~(2+) were 83.8%,92.9%and 94.7%respectively under the condition as follows:molar ratio of DTC unit to heavy metal ions was 4:1,the initial concentration of heavy metal ions was 50 mg/L.Heavy metal ions were absorbed on the foam directly,which could solve the problem that common DTC heavy metal chelating agent which remove heavy metal ions by flocculation produce sludge that was difficultly recycled.
