Abstract: The influence of electron donors,dimethyl sulfoxide (DMSO)and N,N′-dimethylformamide(DMF),on the rate of photo reduction of Cr(VI) to Cr(Ⅲ) was studied.Electron Spin Res-onance (ESR) absorptions and holography indicated that both DMSO and DMF acceleratethe photoreduction of Cr(VI) to Cr(Ⅲ),and DMSO is more effective than DMF.

Key words: electron donor, ESR, holography
