A method for the separation and determination of small amount of zinc in nickel- plating baths is here reported. The dried sample is fused with sodium hydroxide and the water extract is, after suitable treatments, titrated amperometrically with K_4Fe(CN)_6, using a stationary platinum micro-electrode, while the solu,tion is stirred. The optimum conditions are as follows: applied voltage = +0.7 volt, and the supporting electrolyte should be about 0.5 N in NaC1 and 0.4 N in H_2SO_4. With about 0.5% Zn in...
