Degradation of Reactive Yellow 18 Using Ionizing Radiation Based Advanced Oxidation Processes: Cytotoxicity, Mutagenicity and By-Product Distribution

The degradation of Reactive Yellow 18 (RY-18), induced by gamma radiation in aqueous medium, was carried out as a function dose (5–20 kGy) and concentration hydrogen peroxide, the initial dye pH solution were optimized for maximum efficiency. Gamma radiations alone combination with H2O2 used to degrade RY-18. A rate 99% achieved using an absorbed 20 kGy, 0.6 mL acidic pH. Variations functional groups untreated treated RY-18 determined FTIR analysis. LCMS technique determine intermediates formed during process. cytotoxicity mutagenicity studied hemolytic Ames tests, respectively. There significant reductions response treatment. Cytotoxicity reduced from 15.1% 7.6% after treatment kGy H2O2. Mutagenicity 81.3% 82.3% against bacterial strains TA98 TA100 advanced oxidation process efficiency evaluated byproduct formations, which low-molecular-weight organic acid units, through further converted into carbon dioxide water end products. Based on degradation, reduction, has potential removal effluents.
