Abstract

Interactions in the system Pb(NO3)2-Na 2S2O3-(NH2)2CS-H 2O were studied using UV spectroscopy. The results of the study indicate a possibility of complete substitution of thiourea for thiosulfate ions when the solution concentration is 10-3 mol/L. The compounds PbS2O3 • (NH2)2CS • H 2O and PbS2O3 • 2(NH2) 2CS • H2O were isolated from concentrated aqueous solutions and characterized by IR spectroscopy and thermal analysis. The structure of these compounds is suggested. Thermolysis schemes for these compounds are suggested on the basis of the IR absorption spectra of thermolysis products.
