| Abstract: | This paper investigates the photochemical methylation of inorganic mercury in the presence of suifhydryl compounds, L-cysteine and thioglycolic acid, in an aqueoustacetic acid solution of mercuric nitrate. And, the mechanism of the. reaction is also discussed.Methylmercury compounds after having formed in the aqueous solution were extracted and subjected to qualitative and quantitative analyses by thin layer chromatography-mercury analyzer and gas chromatography. As a result, it was found that the yield of methylmercury in the reaction mixture in the presence of sulfhydryl compounds increased significantly. Sulfhydryl compounds act as an effective photosensitizer for photochemical methylation of inorganic mercury therein. |
