| 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。

| Abstract: | 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. |
