| Popis: | Poppy seeds are one of the most important and oldest oil-bearing crops in the world. Therefore, quality control of poppy seeds and food products whose composition contains them as a food additive, is very important. To this end, we have applied procedures for solid-phase spectrophotometric and photometric determining of micro elements in food products. It was established that in determining cadmium and zinc, the best ion exchanger for the group concentration of interfering metal ions is the ion exchanger with the immobilized KO. made it possible to concentrate and determine in the solid phase the ions of Hg(II). Using enabled selective determining of Pb(II). Selective determining of the Fe(III) ions at pH 3 was conducted using ammonium thiocyanate. Cu(II) was determined photometrically upon masking the ions of Fe(III) employing SPADNS. Based on the data acquired, we have developed a microelement analysis scheme for poppy seeds. It was established that the sample contained, mg/kg: Cu(ІІ) – 5.0; Pb(ІІ) – 0.3, Zn(ІІ) – 50, P(V) – 1,600, K − 550, Na – 20, Ca – 1,500, Mg(II) – 450; Fe(ІІІ) −10; Cd(ІІ) and Hg(ІІ) are absent. The proposed scheme for analysis of poppy seeds is universal and could be applied for microelement analysis of other food products. The procedures employed are characterized by sensitivity and selectivity. Ion exchangers with the immobilized dyes, as well as procedures for the solid-phase spectrophotometric determining, are environmentally safe. They do not require the use of toxic organic reagents. The procedures applied are easy to use. Relative standard deviation in the results does not exceed 0.10. This indicates good reproducibility of the results. |
