Abstract

Determination of the arsebic in vegetables by radioactivation and gamma-spectrometry techniques. Activation analysis in combination with γ-spectrometry permits the determination of natural levels of arsenic in plant matter. The isotope As⁷⁶ is utilized for this determination after a chemical separation. This separation is carried out after mineralization (wet-ashing) of the irradiated sample, by precipitation of the As as As₂S₅. The recovery is in the order of 65 per cent for the chemical procedure and the limit of detection for As is 2 × 10^-8g. The main advantage of the described method consists in the speed for serial determinations.
