【摘要】 以凹凸棒土颗粒为载体 ,采用FeCl3为原料 ,制备水合氧化物Fe·nH2 O .然后 ,将氧化物负载在颗粒上 ,制得粒状磷酸根吸附剂 .实验探讨了负载过程中FeCl3的浓度、负载时间、负载温度等因素对吸附剂吸附性能的影响 .结果表明 :在最佳条件下制得的吸附剂其磷酸根的去除率可达 95 4% .更多还原

【Abstract】 A new granulated absorbent for phosphate ions of water was prepared by loading of FeCl 3.H 2O oxides on attapulgite.For this process,such influencing factor as concentration of FeCl 3,time and temperature of the loading process were discussed.The result shows that the rate of removing phosphate ions is 95 4% under the optimal condition.更多还原
