Photo oxidation of iso propanol by uranyl perchlorate in aqueous acid medium

Abstract

Photochemical oxidation of isopropanol by uranyl percholate in aqueous perchloric acid (1.0 M) was studied with visible light of wavelength 436 mμ at 35˚ C.The reduction was followed by measuring the rate of uranous ion production which was found to be proportional to light intensity and to light absorption fraction by the active species .Hydrogen ion concentration, ionic strength, initially added U4+ Decreased the rate slightly Acting as an internal filter. Formation of an intermediate complex between uranyl ion and isopropanol is suggested. Excitation of the complex by light in a primary photochemical act and decomposition of the excited complex by electron transfer mechanism in the dark are suggested to explain the mechanisms of oxidation.
