Application of response surface methodology for optimization of operational variables in photodegradation of aqueous styrene under visible light

摘要: AbstractIn this study, the center composite design in response surface methodology was firstly applied to optimize photocatalytic degradation of aqueous styrene under visible light. Twenty experiments were done by adjusting three parameters (initial concentration styrene, catalyst and initial pH reaction mixture) at five levels method multiple variable analyses. Based on experimental design, an empirical expression established subsequently predict efficiency The results showed that efficiencies are accordance with theoretically predicted values very well a high correlation. strongest interaction between assessed /initial mixture. Optimal conditions for arbitrary 115 mg L−1 found 6.8 loa...
