Scientific foundations of development of new chemically and radiation-resistant cd-containing crystalline materials

Cadmium phosphate Cd_0.5Zr₂(PO₄)₃ was obtained by precipitation from aqueous solutions and studied by means of X-ray phase analysis and IR spectroscopy. The behavior of powdered and ceramic samples in water, aqueous ammonia solutions, nitric acid, EDTA, and also in gamma-radiation fields (⁶⁰Co source), was examined. Experimental characteristics of the chemical and radiation stability are presented.Translated from Zhurnal Prikladnoi Khimii, Vol. 77, No. 8, 2004, pp. 1249–1255.Original Russian Text Copyright © 2004 by Lukuttsov, Spiridonova, Kulagina, Orlova, Petkov, Kulikov.     

Ceramic Cation Exchangers in Ion-Exchange Chromatography

The kinetics of attainment equilibrium in sorption and desorption of sodium and potassium ions with foam ceramic cation exchangers with chemically bound phosphate and vanadate groups was studied.
