Description

To determine solubility of compounds Ak+(B5+UO6)k · nH2O (where A = alkali, alkaline earth metals or 3d transition elements; B P, As or V) in neutral and acid aqueous solutions, procedures are suggested which permit determining components of the difficultly soluble compounds considered as promising matrix materials for radioactive waste immobilization. In particular, a procedure for extraction-photometric determination of uranium(6) was developed and procedures for the determination of vanadium(5), phosphorus(5), and arsenic(5) by photometry were modernized. The solubility of same slightly soluble uranium compounds in aqueous solutions was determined using the procedures

Abstract (Russian)

С целью определения растворимости соединений Ak+(B5+UO6)k · nH2O (где А = щелочные, щелочноземельные или 3d-переходные металлы; В Р, As или V) в нейтральных и кислых водных растворах предложены методики определения компонентов указанных выше труднорастворимых соединений, которые рассматриваются в качестве перспективных матриц для иммобилизации радиоактивных отходов. В частности, разработана методика экстракционно-фотометрического определения урана(6), модернизированы методики фотометрического определения ванадия(5), мышьяка(5) и фосфора(5). С использованием этих методик определена растворимость некоторых малорастворимых соединений урана в водных растворах
