Özet
In this study, Fe-Mn-textile waste material was synthesized from textile waste and the usability for COD and color removal from biologically treated textile wastewater was investigated by S2O82- oxidation process. The prepared Fe-Mn-textile waste was characterized by SEM-EDX and FTIR analysis, and it contains 0.87 +/- 0.03% Fe and 0.42 +/- 0.02% Mn. In the study, persulfate oxidation was carried out at different concentrations of S2O82- and Fe-Mn-textile waste. 51.2% COD and 94.2% color removal was observed at 2.0 g/L S2O82- concentration by UV/ S2O82- oxidation. 61.8% COD and 93.0% color removal have been achieved at 2.0 g/L S2O82- and 7.5 g/L Fe-Mn-textile waste by S2O82-/Fe-Mn-textile waste oxidation. Besides, COD and color removal reached 87.0% and 99.3% in the UV/S2O82-/Fe-Mn-textile waste oxidation process, respectively. The COD removal improvement of the processes followed the order: UV/S2O82-/Fe-Mn-textile waste > S2O82-/Fe-Mn-textile waste > UV/S2O82-. In addition, Fe-Mn-textile waste also has an excellent adsorbent, and 93.2% color and 32.4% COD removal can be achieved as a result of adsorption at 7.5 g/L Fe-Mn-textile waste. In the Fe-Mn-textile waste reusability studies, it was seen that the material could be used effectively three times. As a result, it is seen that the synthesized Fe-Mn-textile waste material is suitable to provide COD and color removal from biologically treated textile wastewater. Thus, both textile waste is reused and low-cost adsorbent or catalyst can be produced.
