本文研究了4-邻氯苯甲酰基-2,4-二氢-5-甲基-2-苯基-3H-吡唑硫酮-3(HCBMPPT)与中性萃取剂磷酸三丁酯(TBP)的甲苯溶液从硝酸介质中对铀(VI)的协同萃取。实验结果表明,其萃取分配比随萃取剂浓度、协萃剂浓度、盐析剂浓度及pH值的升高而增大。同时,对萃合物的化学组成及萃取机理进行了分析和讨论。
In this paper, the effects of 4-o-chlorobenzoyl-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazolethione-3 (HCBMPPT) ) Of toluene solution from nitric acid medium for uranium (VI) synergistic extraction. The experimental results show that the extraction and distribution ratio increases with the concentration of extractant, the concentration of concanders, the concentration of salting-out agent and the increase of pH value. At the same time, the chemical composition of extraction complexes and extraction mechanism were analyzed and discussed.
