Abstract
The kinetic determination of iron and cobalt mixtures without a prior separation is described. The methods are based on the differential reaction rate between pyridoxal thiosemicarbazone and these metallic ions. Various ratios at the 10–5 M level of the two ions can be determined photometrically by using either the “logarithmic extrapolation” or the “single-point” methods. These two methods are compared.Keywords
