| Abstract: | The used activated carbon in decoloration of glycine mother liquor was regenerated by microwave-Fenton reagent oxidation process.The factors affecting the regeneration were studied and the regenerated activated carbon was characterized by SEM.The experimental results show that when n(H2O2)∶n(Fe2+) of the Fenton reagent is 24∶1,the H2O2concentration is 25 mmol/L,the solution pH is 3,the reaction temperature is 55 ℃,the reaction time is 18 min and the microwave power is 600 W,the regeneration rate of the used activated carbon can reach 75.80%. |
