Abstract
A selective and sensitive voltammetric method for the determination of cobalt in vegetable animal foodstuffs is developed. The method is bas ed on the use of alpha-benzil dioxime (alpha-BD) as a chelating agent for differential pulse adsorptive stripping voltammetry (DPASV) and is free from zinc interferences. The influence of pH, time and alpha-BD concentration on the peak resolution and height are discussed. The met hod was successfully applied in some typical vegetable animal foodstuf fs with R.S.D. < 6%.
