Abstract

In this research new catalyst prepared by supporting ZnFe2O4 on Copper Slag (CS) and characterization of this catalyst was done by using Scanning Electron Microscopy (SEM) image, Energy-Dispersive X-ray (EDX) spectroscopy, BET surface area, and X-Ray Diffraction (XRD) patterns. UV + H2O2 processes by ZnFe2O4/CS photocatalyst was used for the degradation of  Resorcinol as a pollutant in water. Circulate Packed Bed Reactor (CPBR) with a total volume of 1 liter and effective volume of 0.2 liters was used in this process. Design of Experiments (DoEs)
was utilized and kinetics of the photocatalytic degradation process was modeled using full factorial design. The experiments were designed considering three variables at three-levels (including pH, the initial concentration of Resorcinol, and initial concentration of H2O2). The results showed that pH=5, the initial concentration of Resorcinol=50 ppm and H2O2 initial concentration=40 ppm had the highest Resorcinol degradation constant rate (k= 3.506 × 10-3).
