Application solutions

Nickel in sodium hydroxide by means of adsorptive stripping voltammetry (AdSV)

To analyze the concentration of nickel in a solution of sodium hydroxide, the solution is first acidified to bring the nickel into its ionic form. The pH is then adjusted to 9.6 with an ammonium chloride buffer. Dimethylglyoxime (DMG) is added to produce a Ni- MG complex, which can be preconcentrated on the mercury dropping electrode. Quantification is by means of standard addition.
