Abstract

Textile wastewater containing synthetic dyes poses serious environmental concerns due to its persistence and toxicity. Although TiO₂, ZnO, and activated carbon-based photocatalysts have shown promising degradation performance, limited studies have explored their integration into photocatalytic reactor systems. Therefore, a UV-assisted TiO₂/ZnO-activated carbon reactor was developed for methylene blue degradation. Therefore, this study aimed to develop and evaluate a UV-assisted photocatalytic reactor employing a TiO₂/ZnO-activated carbon (AC) composite derived from coconut shell waste for methylene blue degradation. This process begins with the production of activated carbon from coconut shell waste, which is ground into a powder and then ground using a mortar and pestle. The powder has activated with H2SO4 and stirred with a magnetic stirrer for 2 hours, accompanied by heating. The powder then filtered and heated in a microwave at 100°C until there is no water content in the carbon. The decrease in the degradation rate observed using a UV-VIS spectrophotometer. Concentration of MB are 50 ppm and 150 ppm, for 60 minutes with an optimal wavelength between 288-300 nm. Degradation efficiency reached 93.5% by 50 ppm, with the absorbance decreasing from 0.347828 at the 20 minutes to 0.064366 at the 60 minutes. Meanwhile, at a concentration of 150 ppm, degradation was recorded at 87.7%, with the absorbance decreasing from 0.494045 at the 20 minutes to 0.122852 at the 60 minutes. These results indicate that the developed UV-assisted TiO₂/ZnO-activated carbon photocatalytic reactor exhibits high performance for methylene blue degradation and offers a sustainable approach for textile wastewater treatment applications.
