[Qualitative and quantitative determination of amino-2 benzimidazole in aqueous medium by polarography (author's transl)].
Amino-2 Benzimidazole, a residue of the decomposition of some fungicides (Benomyl, Carbendazine, Thiophanate, Methylthiophanate), is measured by polarography in aqueous medium, with a platinium rotating electrode, for the exploration in potentials from +0.5 v to 1.4 v. The best conditions for the quantitative determination are investigated, the study according to pH is performed and the standard curve is given for concentrations from 10(-5) to 10(-3) M/l. The interaction of elementts found in tap water and in aquarium water is also investigated.
