It is proposed the method for determination of micro impurities of nitrites and nitrates in the iodides of alkali metals based on the reaction of oxidation of iodides by nitrite ions in the acid medium. It is carried out study of interaction of W(VI) with the brominepyrogallole red in the presence of cetyltriammonia bromide and optimum conditions for associates formation are found. it is established the optimum conditions for decomposition of metal of II group wolframates in the condensed phosphoric acid. there are studied time-temperature characteristics of decomposition of raw material and single crystals of calcium, strontium, zinc and cadmium wolframates.
