The photochemical reduction of uranyl ion with trimethylphosphite and triethylphosphite has been investigated in dry acetone medium in the presence of trimethylacetic acid, using radiation in the visible region (λ ≥ 365 nm). The formation of uranium(V) is supported by the electron spin resonance and electronic absorption spectral data. The quantum yields and Stern-Volmer quenching constants with the substrates have been calculated. With the available evidence an electron transfer mechanism has been postulated for the photochemical reduction of uranyl ion.
