Abstract

Photosonolysis method can be used to degrade humic acid in peat swamp water with the help of ZnO catalyst. This study aims to determine the effect of time variation and catalyst variation on peat swamp degradation. UV-Vis spectrophotometer was used to calculate the absorbance concentration of peat swamp air before and before degradation. The results showed that the highest percentage of peat swamp water degradation was 26.81% at 120 minutes using a ZnO catalyst. The highest degradation of peat swamp water was at 21.99% with a mass catalyst of 0.3 grams of ZnO

Abstract

Research that has been carried out on the photosonolysis degradation of methanyl yellow using a ZnO catalyst aims to determine the effect of radiation time on the degradation of methanyl yellow. The degradation time is about 30 to 150 minutes using a ZnO catalyst. The measurement results of the Uv- Vis spectrophotometer were obtained at a wavelength of 437nm. In the variation of the degradation time, the highest result was obtained at 60 minutes which was 76,11 %. This study showed that the hydroxyl radical (∙OH) was the main control in degrading methanil yellow
