A method is presented for determining the trace amount of chromium in aluminum. Aluminum is dissolved in sodium hydroxide containing hydrogen peroxide. The method is based on the catalytic activity of nitrate ions on the reduction of Cr( 111)-triethylenetetraminehexaacetic acid (-'ITHA) complex. The
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
## 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,
