Determination Of Copper

The principle of our proposed method consists in the sorption of copper-containing urine compounds on an ion-exchange resin (Elgostat type) with the subsequent liberation of the free metal and its spectrophotometry determination in the form of a diethyldithio-carbamate complex.
