Photodegradation and photodecolorization of the samples real textile industrial wastewater is observed directly proportional to pH and catalyst concentrations. Optimum catalyst concentration was found as 2 g l<sup>-1</sup> in both catalysts. COD removal in TiO<sub>2 </sub>assisted system was obtained two fold higher than ZnO assisted system depending characteristics of the wastewater samples. Optimum pH values were determined to be 5 and 9 for TiO<sub>2</sub> and ZnO assisted systems respectively. A COD removal of 45% and 23% were obtained using and ZnO catalysts respectively during 3 h irradiation. The effluents of photocatalytic treated samples using both catalysts displayed no acute toxicity at the end of 3 h irradiation time at optimum experimental conditions. Results, in conclusion, revealed that both TiO<sub>2</sub> and ZnO catalysts were found to be very effective in color removal and provided safe and proper effluents to meet discharge limits, even reuse guideline values. </p> </div> <p> </p> </p></abstract><publication_date><month>10</month><day>01</day><year>2015</year></publication_date><pages><first_page>653</first_page><last_page>663</last_page></pages><publisher_item><identifier id_type="pii">gnest_01715</identifier></publisher_item><doi_data><doi>10.30955/gnj.001715</doi><timestamp>1713922757</timestamp><resource>https://journal.gnest.org/publication/gnest_01715</resource></doi_data></journal_article></journal></body></doi_batch> </div>
