Degradation of cotton textile wastewater using Fenton’s process was investigated. The effect ofindividual and interactive operating parameters on the response was analyzed using central compositedesign (CCD), a commonly used form of response surface methodology (RSM). The operatingparameters selected were pH, dosage of hydrogen peroxide, dosage of iron and the responses (dependentparameters) were chemical oxygen demand (COD) and colour. The model derived correlationcoefficients R2 and R2adj for COD were 0.982 and 0.966, respectively and the values were almostsimilar for colour also. The optimum values for various operating parameters namely pH, H2O2 andFe2+ dosage were found to be 3.33, 60.57 and 1.56 mM, respectively for electrolysis time of 60 min.By performing the experiments with these values of operating parameters, the COD and colour removalefficiencies were found to be 83.5% and 98.1%, respectively.
