Application of response surface analysis to the photolytic degradation of Basic Red 2 dye

In this study, the photolytic degradation of Basic Red 2 (BR2) via UV radiation in the presence of H2O2 was optimized using response surface methodology (RSM). Under the optimized conditions of 20 μM BR2, 1.67 mM H2O2, and pH 7.6, the ANOVA results indicated that the proposed model can be used to navigate the design space. It was found that the response of BR2 degradation is very sensitive to the independent factors of BR2 concentration and H2O2 concentration. In the optimization, R2 and Radj2  correlation coefficients for the model were evaluated as 0.89 and 0.80, respectively.
