摘要
本文报道了D-290树脂吸着UO_(x)Ac_(3)^(-)的机理、交换平衡常数、交换容量、乙酸盐浓度的影响和各种金属离子在D-290树脂上的分配系数等。用此法分离富集铀矿废水中的微量铀,取得了较好的结果。
The papar describes ion exchange behaviour of uranyl in solution of acetate on D-290 resin.The capacity,equilibrium constant and distribution coefficient of uranyl onto D-290 resin were studied by the batch method.In the case of EDTA used as masking agent,this method can be successfully applied to preconcentration by column method and the spectrophotometric determination of trace uranyl in waste water of uranite.
