Al(Ⅲ)—Fe(Ⅲ)复合吸附剂对Cu^(2+)、Zn^(2+)的吸附研究

Adsorption of Al-Fe Complex Absorbents for the Cu2+ and Zn2+ ions.

本文报导了对铀、铜和锌具有一定吸附性能的Al(Ⅱ)一Fe(Ⅲ)复合吸附剂的研制。其中筛选出Al/Fe(摩尔比)=1/0.5,沉淀PH值为8.0,制备温度为40℃的复合吸附剂AF3的吸铜、锌性能最佳。在天然海水中吸铜量和吸锌量分别为12.92微克/克吸附剂和199.4微克/克吸附剂。在50mg/1的Cu^(2+)溶液中吸铜量达到42.5毫克/克吸附剂,在50mg/1的Zn^(2+)溶液中吸锌量达到49.0毫克/克吸附剂。这些结果,对海水综合利用,放射性废液处理,矿业和废水处理都有重要的参考价值。

The screen test of Al-Fe complex absorbents with absorb-ability for uranyl, copper and Zinc ion is reported.The absorbents, in which the Al/Fe( malarrotio ) is equal to 1/0.5 with action temperture is 40℃, PH = 8.0 under precipate, is better for abscrbing uranyl, copper and zinc ion This absorbent of lg absorbs copper of 12.92μg and zinc of 199.4μg in the natural sea water after tendays, but itad sorbs copper of 42.5mg in each gram of absorbent in copperion soladion of 5 Omg/1, it adsorbs Zinc of 49.0 mg in each gram of absorbent in zinc ion solution of 5Omg/l.The results findapplications in sea and waste water or environ mentcl protection.
