Voltametric determination of copper in water samples digested by ozone

The applicability of ozone as a digestion agent in voltammetric trace metal analysis of water samples was investigated. It was shown thatozone efficiently destroys dissolved organic matter, causing a significant decrease of the concentracion of surface active substances in the sample, thus enabling voltammetric measurements. Ozonolysis times of 30 and 60 min were sufficient for the treatment of river water and biologically treated waste water samples, depending on their organic load, prior to voltammetric determinacion of copper using a solid gold electrode.
