Abstract
This work investigates the efficiency of the Fenton process in removing natural organic matter (NOM) from groundwater. Previous studies focused mostly on the use of Fenton’s process to remove total organic matter, but this research also studies the conditions leading to the formation of hazardous disinfection by-product precursors, and their removal. Solutions of a commercial humic acid as a model of NOM and natural groundwater as a real matrix rich in NOM (dissolved organic carbon, DOC=9.92±0.87 mg/L) were studied. Under optimum reaction conditions, the respective removal efficiencies (expressed as DOC) were 95% from commercial humic acid solution and 82% from groundwater. The decrease in DOC resulted in 99% decrease of the content of precursors of trihalomethanes (THMs) and 98% of haloacetic acids (HAAs) for the investigated matrixes. Precursors of haloacetonitriles, haloketones and chloropicrin were detected at much lower concentrations than the THMs and HAAs precursors.
Keywords : Fenton’s process; advanced oxidation process (AOPs); disinfection by-products; natural organic matter
