Abstract
An ultraviolet (UV) absorption method has a difficulty to analyze $ClO_{2(aq)}$ in solutions containing various chlorine species because UV spectrum of $ClO_{2(aq)}$ overlaps with other chlorine-containing species. This study has proposed the deconvolution method of UV spectrum to analyze $ClO_{2(aq)}$ concentration quantitatively in solution containing various chlorine species. We compared results obtained from UV deconvolution method with titration method. Good agreement of $ClO_{2(aq)}$ concentration between them has been shown in about 10%. This result informs us that the deconvolution method of UV spectrum could be a feasible for the analysis of $ClO_{2(aq)}$ in solution containing various chlorine species.
