摘要
用环氧氯丙烷作交联剂、氯乙酸作羧甲基化试剂,合成交联羧甲基木薯淀粉。研究其降低水中的Ca2+含量的效果。结果显示,Ca2+吸附量与交联羧甲基木薯淀粉的取代度、淀粉用量、Ca2+起始浓度、反应时间、温度及pH值有关;交联羧甲基木薯淀粉可降低水中Ca2+含量。
With epichlorohydrin as crosslinker and chloroacetic acid as carboxymethylation reagent, a cross-linked carboxymethyl cassava starch was synthesized and its absorption effects on Ca2+ were investigated. The results showed that the crosslinked carboxymethyl cassava starch can effectively remove Ca2+ from the aqueous solution, and the Ca2+ adsorption quantity is related to starch substitution degree, starch amount, initial Ca2+ concentration, reaction time, reaction temperature and pH value.
