Sobre a Dosagem Fotométrica do Cobre em Águas
The author presents an analytic process for copper quantitative determination in mineral and potable waters, based in the reaction of the cation copper with sodium diethyl-dithio carbamate. Due to the presence of certain elements common in water, such as iron, calcium, magnesium, etc., the main principles of the reactions behavior were studied. In the same manner the reaction sensibility was verified, as well as its precision, by the addition of known quantities of copper. About the end of the work presented, there are shown some copper determinations made through the mentioned process with mineral and potable waters of Paraná.
