Heterogeneous photodegradation of 2,4-dichlorophenol using FeO doped onto nano-particles of zeolite P

Photocatalytic degradation of 2,4-dichlorophenol was studied using FeO-doped onto nano-particles of zeolite P (FeO–NP). FeO/NP was prepared by ion exchange and calcination procedures. The samples were characterized by FT-IR, SEM and DRS. UV–vis, HPLC and COD were employed to calculate the degradation extent of the pollutant. The results confirmed that the degradation efficiency of the method strongly dependent to experimental parameters such as: pH, catalyst concentration, substrate concentration, active component value (FeO) loading, presence of H2O2 and inorganic Cl− and SO42− anions. The first-order kinetics model was used to study the kinetics of the method.
