摘　　要：采用反相悬浮聚合法制备了淀粉接枝丙烯酸/丙烯酰胺高吸水树脂,红外光谱表明接枝成功。对合成产物的保肥性能、吸附性能和降解性能进行了研究,结果表明:在土壤中加入吸水树脂,可在一定程度上改善土壤对氮、磷、钾肥料养分的吸附能力,提高土壤保肥能力。合成树脂对金属离子Ca^(2+)、Mg^(2+)和Ba^(2+)有较好的吸附性;合成树脂在紫外光照射下有较好的降解率。Starch graft acrylic acid/acrylamide high absorbent resin was prepared by reversed phase suspension polymerization.Infrared spectroscopy showed graft success .Protecting fertilizer adsorption and degradation performance of synthetic product were studied , the results showed that the resin can improve N , P, K nutrient adsorption ability of the soil to a certain extent.Synthetic resins have good adsorption to the metal ions for Ca 2＋, Mg2＋and Ba2＋; synthetic resin has good degradation rate under UV irradiation .
