STUDY ON THE EXTRACTION OF SILVER NITRATE BY PRIMARY AMINE N1923
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.
