Synergistic influence of Zn(II) in the extraction-atomic-absorption determination of trace cadmium in waters
A very simple and rapid procedure is described in which the addition of a large amount of Zn(II) to a water sample before extraction by 2-mercaptobenzothiazole into n-butyl acetate brings about almost total extraction of Cd and allows determination of concentrations down to at least 0.02 ng/ml. High...

| Summary: | A very simple and rapid procedure is described in which the addition of a large amount of Zn(II) to a water sample before extraction by 2-mercaptobenzothiazole into n-butyl acetate brings about almost total extraction of Cd and allows determination of concentrations down to at least 0.02 ng/ml. High precision is achieved, and the interference of cyanide is also overcome. |
