Response Surface Methodology for Optimization of Bisphenol A Degradation Using Fe3O4-Activated Persulfate

In this study, the degradation of bisphenol A (BPA) by a magnetite (Fe3O4)/persulfate (PS) system was investigated. The effects dosage, PS concentration, BPA and pH on Fe3O4-activated in degrading were investigated using single factor experiments. identified as factors response surface experimental protocol. Using Box-Behnken analysis, quadratic model with high correlation coefficient (0.9152) obtained, which accurate predicting results. optimal parameter conditions obtained methodology (RSM) [magnetite] = 0.3 g/L, [PS] 0.26 mM, 4.9, under predicted rate 59.54%, close to real value.
