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。

关键词: 红薯淀粉, 交联羧甲基, Ca2+

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.

Key words: cassava starch, cross-linked carboxymethyl, Ca2+
