DETERMINATION OF METALS CONSISTS IN REGUL, THE RAW RICE SORT
Description
The content of metals in raw rice is determined. Inversion voltammetry (IVA) was carried out in an accredited laboratory on the "Ta-Lab" device of the company "Tom-Analit" LLC according to the approved method of ERD F 16.1: 2: 2.2: 2.3.46-06. Silicon dioxide is determined according to ERD F 16.1: 2: 2.2: 3.65-10 and humidity according to GOST 5180-2015. Preparation for the IVA is illustrated. Voltammograms of the potential difference of the chloride-silver reference electrode are compared with the current strength of the indicator mercury-film electrode of electrochemical cells. It has been established that the main metals of the raw rice called Regul grown in the Krasnodar region are: copper 1.6 ± 0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5 mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and silicon dioxide 6.5 mg/kg. The presence of iron is associated with the wear of gravity. The content of zinc, manganese and silicon dioxide corresponds to this type of grain. The presence of copper and lead is associated with the absorption of heavy metals from the soil
