Determination of arsenic in water samples treated with ozone

The applicability of ozone as a digesting agent in the trace analysis of arsenic in natural water samples has been investigated. Differential pulse polarographic (DPP) and sprctrophotometric methods were applied and compared. No significant differences were found between the results of the DPP and spectrophotometric measurements in natural ground water samples. Thus, ozone treatment may, in some cases, successfully be used for sample pre-treatment prior to either of these analytical methods. Key words: DPP, Spectrophotometry, determination of arsenic, ground water, ozone treatment.
