摘要: <正> 关于强碱性季铵型阴离子交换树脂在铀酰的硫酸盐溶液中吸附平衡的研究,虽然有不少报道。但是,对于组成接近铀水冶条件的溶液中吸附平衡的研究是相当不充分的。本文采用化学当量法研究了上述树脂在这种溶液中的吸附平衡。 强碱性季铵树脂从铀酰的硫酸及硫酸钠溶液中吸附UO_2(SO_4)_3~(4-),UO_2(SO_4)_2~(2-),SO_4~(2-)及HSO_4~-四种离子。我们用硝酸钠溶液将它们一起洗脱下来,测定相应组分的含量。由于Abstract: The exchange equilibrium between SO42- and HSO4- on quaternary ammoniur strong base resin and effect of CIO4- on the equilibrium by chemical equivalent method are studied in this paper. On the basis of the results the adsorption equilibrium of the resin in uranyl sulphate solution which is similar to the solutio in uranium hydrometallurgy process is also studied.
