摘　　要：本文以羧甲基马铃薯淀粉、丙烯酸(AA)及其钾盐、丙烯酰胺(AM)为原料合成了含钾、氮高吸水树脂,主要考察了丙烯酸的中和度、单体配比、Fe3+的初始浓度对废液中Fe3+的吸附容量和脱除率的影响。研究结果表明:以羧甲基马铃薯淀粉为原料合成的含钾、氮高吸水树脂对Fe3+的吸附性能较好,其最高吸附容量为100mg/g。In this paper, a kind of super absorbent resin were synthesized by graft copolymerization of A- crylic acid （AA） and its potassium salt / acrylamide （AM） onto carboxymethyl potato starch. The influ- ence on adsorption capacity and removal rate, such as neutralization degree, mass ratio of AA and AM, concentration of Fe3＋ were discussed. The results show that super absorbent polymer has the better adsorption effective for Fe3＋, the maximum adsorption capacity is 100mg/g.
