摘要: 本文用两相滴定法研究了1-苯基-3-甲基-4-苯甲酰基-5-吡唑酮(PMBP,简写为HA)与甲基膦酸二(1-甲基庚基)脂(P350,简写为B)对Pb2+、Cd2+和Cu2+离子在不同的有机溶剂中的萃取机理.确定了萃合物的组成分别为:MA2(M=Pb2+、Ca2+、Cu2+);MA2·HA(M=Cd2+);MA2·B(M=Pb2+、Cd2+)和MA2·2B(M=Cd2+),同时求得了相应的萃合常数β值. |

Abstract: The chclatc extraction of Pb(Ⅱ), Cd(Ⅱ)and Cu(Ⅱ)with PMBP(HA)in benzene and syncrgistlc extraction of Pb(Ⅱ)and Cu(Ⅱ)with PMBP and P350(B)in each of eight organic solvents were investigated by using the two-phase titration method. The formulas of the extracted species have been suggested and the extracting equilibrium constants B2im corresponding to the extracted chclatcs MA2(HA)i mB have been evaluated(abbreviated). |
