摘要
用斜率法和等摩尔系列法确定了三元萃合物的组成,比较了不同中性膦(磷)对Re(Ⅶ)萃取的协同效应,用红外光谱研究了萃合物的键合情况,计算了萃取过程的热力学函数.
The composition of extracted complexes of rehenium (Ⅶ) by N1923-TBP system is inferred with the methods of slope and constant mole. The bond-coupling among the atoms of extracted compound is studied by the IR spectra. And the thermodynamic functions of extracting reaction are determined.The results indicate that the composition of extracted complexes is N1923.2HReO4 2TBP, and molecules among N1923, HReO4 and TBP are combined by H-bond. The reaction is an exothermic reaction and high temperature is unfavourable to the extracting Re(Ⅶ).
