The Sonocatalytic Activation of Persulfates on Iron Nanoparticle Decorated Zeolite for the Degradation of 1,4-Dioxane in Aquatic Environments

In the chemical industry, 1,4-diethylene dioxide, commonly called dioxane, is widely used as a solvent well stabilizing agent for chlorinated solvents. Due to its high miscibility, dioxane ubiquitous water contaminant. This study investigates effectiveness of catalyst- and ultrasound (US)-assisted persulfate (PS) activation with regard degrading dioxane. As first step, composite catalyst was prepared using zeolite. A sonochemical dispersion reduction method dope zeolite iron nanoparticles (FeNP/Z). subsequent study, reaction kinetics degradation following single-stage two-stage addition PS examined in presence catalyst. Using GC-MS analysis, intermediate compounds formed from were identified, plausible pathways described. Upon 120 min sonication injection PS, 95% 100 mg/L degraded. Finally, estimated cost treatment also reported this study. Sonolytically activated combined FeNP/Z synergizes remediation biorefractory micropollutants such
