摘要： 本文研究了伯胺N1923萃取AgNO3的性能及不同因素对其分配比的影响,通过多种方法确定其萃合物的组成为[Ag(RNH2)2]NO3;测定并计算出该反应的表观平衡常数及热力学函数,同时分析了萃合物的红外及核磁共振谱。

Abstract: In this paper silver nitrate was extracted by N1923 quantitatively at pH=3. The effects of the acidity, concentration of NO3- and temperature on the distribution ratio D have been investigated. A mechanism of the extraction has been proposed from the results obtained by using chemical equilibrium method, constant mole method and the saturation method. It was found that the extracted compound haS a formula of Ag (RNH2)2NO3 formed by coordination bond of Ag-N. Some thermodynamics functions of the extraction process and IR and NMR spectra of the compound were discussed as well.
