| Abstract: | Conducting anodic stripping voltammetry (ASV) to determine non-labile-form metal in a water sample usually requires UV digestion. The time for thoroughly disintegrating metal complexes is lengthy and completion of digestion is not easy to determine. In this study, the degree of dissociation of copper complex, indicated by the ratio of slope changes at ASV titration, was found to be linearly correlated with UV irradiation time (r 2 = 0.976). Using slope changes, an equation for estimating the length of UV ir... |
