Precipitation of nickel dimethylglyoximate.
The homogeneous precipitation method of Salesin and Gordon and the aqueous acetone precipitation described by Jones and Howick are examined for the determination of nickel as the dimethylglyoximate and where applicable comparisons are made with a direct (conventional) precipitation of this substance. The co-predpitation of iron and cobalt was studied radiometrically under various experimental conditions. Relevant solubility data are also presented. Application of the methods to the determination of nickel in alloy steels showed that in the absence of cobalt there is little to choose between them. For cobalt steels the method of Jones and Howick is more convenient than that of Salesin and Gordon and more satisfactory than a conventional precipitation and gravimetric finish.
