Abstract The determination of anions in aqueous solution using an ArF laser is described. Chloride ion can be determined down to a level of $4×10^{-7}M$ by measuring the absorption of Cl formed by ArF laser irradiation using a multiple-reflection method with a helium-cadmium laser (λ=325nm) as the monitoring light source. $Br^{-},$ $I^{-},$ $SCN^{-}and$ $SO_{4}^{2-}were$ determined by measuring the absorption of radicals or hydrated electrons formed upon UV laser irradiation with detection limits of $4×10^{-7},$ $4×10^{-7},$ $1×10^{-6}-and$ $1×10^{-4}M,$ respectively.
