Bisulfite reaction

Web摘要： The improvement on diclofenac (DCF) degradation by Fe(II)-activated persulfate (PS) combined with bisulfite (BS) was investigated. It was observed that the introduction of BS in Fe(II)/PS process enhanced the circulation of Fe(III/II) and kept Fe(II) at a high concentration, resulting a rapid and continuous DCF degradation. The safety of cosmetic products is constantly in question as the components are always changing or being discovered as a possibly harmful substance. The sulfite components of cosmetic ingredients, such as sodium bisulfite, underwent clinical trials to find out their safety in cosmetic formulations. Sodium bisulfite functions as a reducing agent and furthermore as a hair-waiving/straightening agent. As of 1998, sodium bisulfite was used in 58 different cosmetic prod…
