Abstract

The article presents the findings of the study of the interaction of salt V(+5) with caprohydroxamic acid in water-alcohol solutions. The compositions of the resulting complex compounds were determined by the method of A.K.Babko, their instability constants in water and its mixtures with 20; 40; 60; 80 volume percent content of methanol, ethanol and propanol were calculated. It was found that the stability of complex compounds V(+5) increases with an increase in alcohol content in the mixture. The optical density of the solution at λmax = 450 nm is the highest in aqueous propanol solutions. It has been concluded that the data obtained can be used in the development of conditions for the determination of vanadium content by photocolorimetric method
