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
