Heterogeneous photodegradation of 2,4-dichlorophenol using FeO doped onto nano-particles of zeolite P
E-mail:
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 SO4 2- anions. The firstorder kinetics model was used to study the kinetics of the method.
