| Abstract: | The Fenton degradation of methylene blue was studied under different experimental conditions using ferrous-substituted resin as catalysts in presence of H2O2.An initial methylene blue concentration of 2.5 mmol/L was used as representative of a methylene blue industrial wastewater.159.13 mg/g ferrous-substituted resin showed the maximum efficiency in the degradation of methylene blue.The optimum operation conditions were initial concentration of H2O2 15 mmol/L,pH 4.0,260 min of reaction time,catalyst dosage 3 g/L.The degradation rate of methylene blue was up to 99.32 % under the operation conditions.The catalyst could be reused for many times. |
