【摘要】 将蔗渣纤维素进行碱活化处理后与乙二胺四乙酸二钠在KMnO4/H2SO4引发下进行接枝共聚反应,然后在碱性条件下与CS2作用可得兼具氮、硫元素的纤维素吸附剂,该吸附剂对Cu(Ⅱ)、Cr(Ⅵ)、Pb(Ⅱ)、Zn(Ⅱ)等重金属离子有良好的吸附作用。更多还原

【Abstract】 The bagasse cellulose was treated with sodium hydroxide,and then the graft copolymerization was reacted between alkli-celluse and EDTA.The graft copolymer reacted with carbon disulfide to get the cellulose adsorbent contained sulfur and nitrogen.This cellulose adsorbent had good adsorption for Cu(Ⅱ)、Cr(Ⅵ)、Pb(Ⅱ) and Zn(Ⅱ).更多还原
