The Response Surface Methodology to Optimize the Catalytic Degradation of 4-Chloro 2-Nitro Phenol

Abstract

<span style="font-size: 9pt; mso-bidi-font-family: 'Times New Roman';"><span style="font-family: Times New Roman;">The catalytic degradation of 4-chloro 2-nitro phenol aromatic compound has been studied with coupled ozone-sonolysis method. The response surface methodology was used to optimize the influence of operation parameters on the catalytic degradation of 4-chloro 2-nitro phenol. In order to evaluate the influence of operation conditions in the degradation of 4-Chloro 2-Nitro Phenol, four independent variable chosen: 4-Chloro 2-Nitro Phenol concentration, mass flow rate of O₃, TiO₂ concentration and ultra sonic power. Analysis of variance was employed to consider main factors effects and interactive effects in the optimization of catalytic degradation of of 4-Chloro 2-Nitro Phenol. Analysis of variance results present that the model is statistically significant. The response surface methodology predictions were in agreement with the experimental values.</span></span>
