Abstract

Background and objectives: The CHROMIUM compounds could be hazardous to human’s health. The aim of this study was to compare the Performance of Electro-Fenton and FENTON PROCESS in the removal of CHROMIUM in presence of CYANIDE as an Intermediate in aqueous.Material & Methods: In this experimental study, a reactor with 1 liter useful volume was used. Four electrodes made of iron were used in EF. Parameters of study including pH, Voltage, initial concentration of CHROMIUM, H2O2 and CYANIDE as an intermediate in EF process and pH, concentration of Fe ions, initial concentration of CHROMIUM, H2O2 and CYANIDE as an intermediate in F process were examined.Results: The results showed that efficiency of EF process in pH=3, Voltag = 20V in 100 mg/lit CHROMIUM, was 97%. Also in F process in optimum condition with pH=3, Fe ions = 500mg/lit, H2O2 = 50ml/lit and CHROMIUM concentration = 100 mg/L efficiency was 90%. By CYANIDE addition reactor efficiency was decreased.Conclusion: EF process outperformed FENTON PROCESS in removal of CHROMIUM compounds.
