Abstract

With the aim of simplifying and accelerating the voltammetric analysis of foodstuffs, it is proposed that ultrasound be used in the acid digestion of samples, voltammograms be recorded without removing oxygen, to determine arsenic(III) be determined directly in salts and food supplements soluble in the supporting electrolyte, and arsenic be distilled off. Sample preparation with the distillation of arsenic trichloride from the sample solution is an alternative to wet and dry ashing in the analysis of all type of foodstuffs and various waters.
