Ozone catalytic oxidation of dimethyl sulfide and surface analysis of iodine catalyst

Abstract This study, reports on ozone catalytic oxidation of dimethyl sulfide; a major odor material waste water facilities. Xenon excimer lamp (XEL) was used for generation, and iodine compounds (I- IO3-) were utilized as catalyst. Three types activated carbon, carbon impregnated with sulfate (AC-I/S), (AC-I) without impregnation (AC) tested catalysts. Only AC-I/S had activity in the dynamic adsorption experiment. Breakthrough time sulfide increased by 10 times adding AC-I/S. Catalyst characterization pH measurement XPS analysis suggested that influenced surface acidity. These results suggest XEL are applicable gas treatments.
