Abstract

An adsorptive stripping voltammetric (AdSV) procedure is proposed for determination of folic acid (FA) in cores and coated pellets of Hemofer (FA/iron tablet). The adsorptive stripping response was evaluated with respect to the electrolyte solution, the accumulation time and potential, and the concentration dependence. The relationship between i~p~ and FA concentration was linear over the range 1 × 10^−8^ to 5 × 10^−7^ M FA. The conditions of cores and pellets preparation for analysis were established. The relative standard deviation is 2.4% for a content of FA of 0.35 mg per core (n = 5).

Germanium is detrimental to the electrochemical deposition of zinc. Consequently, its concentration needs to be monitored in an electrolytic zinc plant. Pyrocatechol violet can be used as a complexing agent with germanium. Adsorption of the complex followed by reduction allows a sensitive differenti
