本文以红薯淀粉为原料，氢氧化钠为催化剂、环氧氯丙烷为交联剂制备交联淀粉，在此基础上，以交联淀粉为原料，GTA（2,3－环氧丙基三甲基氯化铵）为醚化剂，采用微波辅助半干法制备了交联醚化淀粉，研究了交联醚化淀粉对废水中金属离子Ag+、Cu2+、Zn2+、Cr6+的吸附性能。实验结果表明：增加交联醚化淀粉投入量有助于提高吸附性能，当其投放量为0.7g，废水pH在6.5时，吸附效果最佳。
本文以紅藷澱粉為原料，氫氧化鈉為催化劑、環氧氯丙烷為交聯劑製備交聯澱粉，在此基礎上，以交聯澱粉為原料，GTA（2,3－環氧丙基三甲基氯化銨）為醚化劑，採用微波輔助半榦法製備瞭交聯醚化澱粉，研究瞭交聯醚化澱粉對廢水中金屬離子Ag+、Cu2+、Zn2+、Cr6+的吸附性能。實驗結果錶明：增加交聯醚化澱粉投入量有助于提高吸附性能，噹其投放量為0.7g，廢水pH在6.5時，吸附效果最佳。

Preparation of cross-linked starch was studied with sweet potato starch as raw material, sodium hydroxide as catalyst and epichlorohydrin as cross-linking agent. Then cross-linked etherification starch was prepared using microwave-assisted semidry process, with cross-linked starch as raw material, GTA for etherification agent. And its adsorption performances to metal ions Ag+, Cu2+, Zn2+, Cr6+ in wastewater were studied. The results showed that increased cross-linked etherification starch inputs could help improve the adsorption properties. The adsorption effect could be best when the dosage of cross-linked etherification starch was 0.7g and the pH of wastewater was 6.5.
