Information × Registration Number 0207U000995, 0104U004223 , R & D reports Title Development of the determination procedures of quality indexes on agricultural row materials and produce of Lead, Cadmium, Copper and Zinc contents. popup.stage_title Head Volodymyr Kopilevich, Registration Date 02-03-2007 Organization Ukrainian Laboratory of Quality and Safety of Production of AIK NUBiP of Ukraine. popup.description2 Object of research - waters, soils, fertilizers, vegetable row materials, fodders and foods. Aim of research - carrying out of the systematic investigations of analytical determination of quality indexes of natural water, vegetable row materials, fertilizers and soils as content of Lead, Copper, Zinc and Cadmium for determination procedures development of their micro quantities of sufficient accuracy. Method of research - electrochemical method of chronopotentiometry. It was presented determination procedures with using of analyzer М-ХА1000-5 and was done its metrological attestation, when it was determined the optimum concentration of Pb, Cu, Zn, Cd in solution near 0,01 ?g/l with relative error 1,3-1,7%; it was done the comparative measuring of Lead, Copper, Zinc and Cadmium content in foods, milk, sugar and sugar beet using methods of nverse chronopotentiometry, atomic-absorbtion spectrometry and visual spectrometry, which was shown the sufficiently high level of results coincidence with relativedeviation 2-14 %. Results of research may be used in practice of measuring laboratories and checkpoints and research laboratories of scientific institutions.
