摘　　要：以麦秸秆为原料制备纤维素黄原酸酯(CX),研究其对重金属离子Cu^(2+)、Zn^(2+)、Pb^(2+)、Cr^(2+)、Ni^(2+)的吸附能力,及再生性能。结果表明,CX对各重金属离子吸附率达到90%以上,其中对Cr^(2+)、Ni^(2+)金属离子吸附率最高,对Cu^(2+)吸附率最低,而且CX经四次再生,回收率仍在75%以上,对铜离子的吸附率也在70%以上。Cellulose xanthate(CX)was prepared from wheat straw as raw material.The adsorption capacity and regeneration performance of CX on heavy metal ions Cu^(2+),Zn^(2+),Pb^(2+),Cr^(2+),and Ni^(2+)were studied.The results show that the adsorption rate of CX for heavy metal ions is more than 90%,of which the adsorption rate of Cr^(2+)and Ni^(2+)metal ions was the highest,and the adsorption rate of Cu^(2+)was the lowest.Moreover,the recovery rate of CX is still more than 75%after four regeneration times,and the adsorption rate of copper ion is also more than 70%.
