树脂对某铀铁共生矿井下废水中铀的吸附性能
|
摘要
研究201×7和D363B树脂对某铀铁共生矿的矿井水中U(Ⅵ)的吸附性能。结果表明:2种树脂吸附效果都较好,201×7树脂吸附容量大于D363B树脂,宜选用201×7树脂。选择接触时间的一半(2.5min)更利于实际生产。对201×7树脂的淋洗和多次循环吸附性能的研究表明,201×7树脂有效容量为12.36g/L,对U(Ⅵ)回收率可达到70.2%,经6次循环吸附,仍保持着较好的吸附性能。
The performances of adsorption of 201×7 and D363B resins for adsorbing U(Ⅵ)from effluent in the pit in one uranium iron paragenic ore were studied.The results of adsorption show that both resins have higher adsorption capacities,while the adsorption capacity of 201×7 is greater than that of D363B resin,and 201×7 resin is selected for this effluent treatment.The resin contact time for adsorption is 2.5 min more appropriately for the production.The desorption and manifold cycles adsorptive property were carried out in this experiment and the results show that the adsorption capacity of wet 201×7 resin is 12.36 g/L,the recovery rate of U(Ⅵ)is 70.2%.Through six cycle adsorption,201×7 resin shows better adsorption capacity.
