The gravimetric determination of nickel with ...

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 p H of 5.5–6.5. The solubility of the nickel dimethylglyoxime complex has been determined as a function of temperature, p H and alcohol …

Figure 1.1 Fresenius' analytical scheme for the gravimetric analysis of Ni in ores. Note that the mass of nickel is not determined directly. Instead, Co and Ni are isolated and weighed (mass A), and then Co is isolated and weighed (mass B). The timeline shows that after digesting a sample, it takes approximately 44 hours to complete an analysis.
