| Abstract: | Abstract Three programs develpoed to analyze data for liquid-liquid extraction of metal have been applied to the calculation of the stability constants of aqueous cadmium(II)-thiocyanato complexes by using the data for the extraction of tricaprylmethylammonium salt in benzene. The resulting stability constants of the aqueous thiocyanato complexes determined were: for the trial and error method log β1 = 2·97, log β2 = 3·70, log β3 =3·50 and log β4 =3·28; for the Gauss method log β1 = 2·91, log β2 = 3·70, log β3 =3·35 and log β4 = 3·29; for the Newton-Gauss method for log β1 = 2·47, log β2 =3·24, log β3 =2·29 and log β4 = 2·85 |
