The effects of solvents, pH, and concentration on the photolysis of CH3I were investigated. It was found that CH3I undergoes faster photolysis in aqueous solution and produces I-2 and I-3(-).
In this work, the effects of the solvents, pH, and concentration on the photolysis of CH3I under UV irradiation were investigated. The photolysis of CH3I mainly occurs in the gas phase and is faster in its aqueous solution compared to in its n-hexane and methanol-water solutions. UV irradiation-induced photolysis of CH3I produces I-2 and I-3(-) whereas the formation of the latter is affected by the former. In addition, both the pH and concentration of CH3I aqueous solutions affect the formation and transformation of I-3(-) and I-2. The results are helpful and referable to understanding the photolysis behavior of CH3I under UV irradiation.
