Özet
In this study, Fe-Cu-Pumice (Fe-Cu-P) composite was prepared to attempt it for UV/Fenton-like treatment of biologically treated textile wastewater by means of COD andcolor removal. SEM-EDX analysis showed that Fe-Cu-P composite contained Fe and Cuat 3.5% of each one. More than 95% color (RES-436, RES-525, RES-620) removal couldbe achieved using 3 g/L Fe-Cu-P in the Fenton-like process. The removal of COD and absorbances at Abs-254 nm and Abs-280 nm increased up to 5 g/L Fe-Cu-P concentration.In addition, the highest COD, Abs-254 nm and Abs-280 nm removal could be achievedat 250 mg/L H2O2 concentration pH 3. The removals of COD, Abs-254 nm and Abs-280nm were obtained to be 63.7%, 66.3% and 72.9%, while the removals of RES-436, RES-525and RES-620 were observed as 92.9%, 96.7% and 98.1%, respectively at optimum doses ofcatalyst (5 g/L Fe-Cu-P), oxidant (250 mg/L H2O2) and pH 3 after 3 h oxidation at roomtemperature
