Abstract
Several articles (1,2,3A ) have appeared in which metal-thiourea complex formation constants have been calculated from the half-wave shifts of the complexes. However, the Lingane and DeFord-Hume Equations which were used can only be applied to the complexes of reversible metal ions. | The purpose of this work was to explore an extension of the DeFord-Hume Equation to calculate the complex formation constants of an irreversible metal ion, in this case Ni (IT). In order to use the method previously used by Crow and Westwood (5), a reversible metal-thiourea system had to be studied thoroughly. To make full use of the data, a computer least squares program was used to solve a set of simultaneous equations, as Klatt and Rouseff proposed (6 ). The nickel(II)-thiourea complex formation constants should then be calculable from the effect of Ni(II) on the Pb(II) wave.
