  摘要：

  Interactions in the system Pb(NO(3))(2)-Na(2)S(2)O(3)-(NH(2))(2)CS-H(2)O 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 PbS(2)O(3) center dot (NH(2))(2)CS center dot H(2)O and PbS(2)O(3) center dot 2(NH(2))(2)CS center dot H(2)O 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.

  We have studied the thermolysis of lead thiosulfate thiourea complexes in a nitrogen atmosphere at temperatures from 20 to 500 degrees C. The thermal decomposition products have been characterized by X-ray diffraction, IR spectroscopy, and mass spectrometry at different stages of the process. The structure of the complexes and the thermolysis mechanisms are discussed.
