Abstract

A Novel Integration of CWPO Process with Fe3O4@C and Sonication for Oxidative Degradation of 4-Chlorophenol

Highlights

  • 4-Chlorophenol (4-CP) is an organo-chlorine compound extensively used in pharmaceutical, petrochemical, organic chemical manufacturing, and dye industries.[1]

  • Our findings indicated that the pHzpc of the catalyst was 7 (Fig. 4b); at acidic conditions when the solution pH is lower than

  • The efficiency of catalytic wet peroxide oxidation (CWPO) process was enhanced with sonication and Fe3O4@C as a heterogenic catalyst for removal of 4-CP in aqueous solution

Summary

Introduction

4-Chlorophenol (4-CP) is an organo-chlorine compound extensively used in pharmaceutical, petrochemical, organic chemical manufacturing, and dye industries.[1] United States Environmental Protection Agency (USEPA) has introduced 4-CP as a priority pollutant due to carcinogenicity, persistence, and toxicity.[2] investigation of treatment methods for degradation of 4-CP from waste streams is considered by researchers Physicochemical treatment methods such as adsorption, precipitation, conventional oxidation, coagulation, and membrane filtration have demonstrated several drawbacks such as low efficiency, high cost, and limited capacity for high concentrations of pollutant.[3] biological methods are not suitable due to low efficiency, long time required, and production of high. The present study aimed to investigate a novel integration of CWPO process with Fe3O4@C and sonication for oxidative degradation of 4-chlorophenol
