Ionometric Determination of Cadmium (II) in the Form of Halide Anion Complexes

The possibility of ionometric determination of Cd (II) in the form of halide anion complexes was shown. The main characteristics of the ion-selective electrode were studied. It is found that cations Al3 +, Ca2+, Cu2+, Zn2+ up to 50 fold excess do not prevent the determination. The relative standard deviation for the determination of cadmium (II) at 3,0 ∙ 10-4 mol / l in the presence of other ions is no more than 0,06.
