Determination of stability constants of cadmium(II) with some amino-acids by use of an ion-selective electrode.
Three different methods were used to obtain the stability constants of the complexes of cadmium with several mino-acids. Two made use of an ion-selective electrode; the third was based on pH-measurement only. Values of beta(ml) and beta(ml)(2) obtained in 0.1M KNO(3) at 25 degrees corresponded reasonably for most amino-acids examined and accorded with the values given in the literature, as far as comparison was possible.
