Abstract
The determination of nickel in high cobalt alloy and cobalt metal was Studied. Nickel less than 10% must be precipitated and estimated with dimethylglyoxime by means of cyanide-aldehyde method, and that less than 0.3% in cobalt metal must be estimated colorimetrically with dimethylglyoxime. 0.001% nickel in cobalt is determinate by this colorimetrical method.
