    Activation analysis in combination with γ spectrometry permits
    the determination of low concentrations of molybdene in small amounts of
    plant matter. The Isotope Mo99 Is utilized for this determination since
    it has a suitable half-life and since its parent compound Mo98 is abundant. A preliminary chemical separation is necessary and is carried out
    after mineralization of the sample by precipitation of the Mo with α-benzoïne
    oxime. The precipitate is then redissolved and extracted Into isoamyl
    acetate In the presence of KCNS. The recovery is of the order of 70 % for the Chemical procedure. The limit of detection for Mo is 10-7g.
    The Standard error of the method is 15% for concentrations of Mo In the
    order of 1 ppm .
