The effect of various operating parameters, such as pH of batik wastewater, catalyst dosage and aeration on the photocatalytic degradation process, was examined. The mineralization of batik wastewater was also evaluated through chemical oxygen demand analysis. The decolorization of batik wastewater was enhanced at acidic conditions (pH3) which was 88.2% after 10 h irradiated under solar light, meanwhile its mineralization was 286 mg/L after 12 h irradiation time. The data obtained for photocatalytic degradation of batik wastewater was well fitted with the Langmuir-Hinshelwood kinetic model. It can be concluded that batik wastewater could be decolorized and mineralized under solar light irradiation with presence of ZnO. 2016-06-25T03:40:24Z 2016-06-25T03:40:24Z 2015-04-01 Article Sains Malaysiana, vol.44 (4), 2015, pages 607-612 0126-6039 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/42192 en Penerbit Universiti Kebangsaan Malaysia
