A combined treatment approach using Fenton's reagent and zero valent iron for the removal of arsenic from drinking water

摘要

Studies on the development of an arsenic remediation approach using Fenton's reagent (H_2O_2 and Fe(II)) followed by passage through zero valent iron is reported. The efficiency of the process was investigated under various operating conditions. Potable municipal water and ground water samples spiked with arsenic (III) and (V) were used in the investigations. The arsenic content was determined by ICP-QMS. A HPLC-ICPMS procedure was used for the speciation and determination of both As (III) and (V) in the processed samples, to study the effectiveness of the oxidation step and the Subsequent removal of the arsenic.
