Abstract
Kinetic modeling using multivariate curve resolution-alternating least squares (MCR-ALS) was performed successfully for the electro oxidation (EO) treatment of textile wastewater. The present study represents the monitoring of the % degradation and kinetics of the EO reaction during the treatment of textile effluent. Optimum condition was found to be t = 130 min, i = 1.41 A, pH = 5.41 and Retention time = 143 min. At this optimum condition, the degradation suggested by response surface methodology (RSM) under central composite design (CCD) was 86%. A good correlation was observed between the predicted and experimental % degradation at the optimum value of process parameters. Spectrophotometric data of EO process during the treatment of textile effluent was analyzed during MCR-ALS. ALS optimization was performed by applying a series of constraints. The initial and final concentration of the pollutants along with the kinetic parameters were successfully resolved. The performance of kinetic modeling on predicting EO treatment was evaluated by a lack of fit in % experimental (1.215) and explained variance (99.98%).
