Summary

A detailed investigation has been made of the gravimetric determination of nickel with dimethylglyoxime in the presence of copper. Copper interference is eliminated by precipitation in a solution containing tartrate and thiosulphate at a pH of 5.5–6.5. The solubility of the nickel dimethylglyoxime complex has been determined as a function of temperature, pH and alcohol concentration.
