摘　　要：研究了4种双吡唑啉酮类萃取剂(H_2A)对UO_2^(2+)的萃取。该类萃取剂带有两个1-苯基-3-甲基-4-酰基吡唑啉酮-5,中间带有低聚亚甲基—(CH_2)_n—(n=2、3、4及6)作为桥。萃取的结果表明,该体系形成UO_2HA及UO_2(HA)_2配合物。还求出其平衡常数并探讨其萃取机理。A family of bis(4-acylpyrazol-5-one) derivatives in which two 1-phenyl-3-methyl-4-acylpyrazol-5-one subunits are linked by a polymethylene chain - (CH2)n- of lower length ( n = 2, 3,4 ,6) have been designed. The extraction reaction and their equilibrium constants were found. The mechanism of extraction was discussed.
