Abstract

Activation analysis in combination with γ-spectrometry permits levels of arsenic in plant matter . The isotope As⁷⁶ is utilized for this determination after a chemical seperation. This separation is carried out after mineraIization (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 x 10^-8g.
The main advantage of the described method consists in the speed for serial determinations.
