Инверсионно-вольтамперометрический контроль тяжелых металлов в шампунях

Abstract

Методом инверсионной вольтамперометрии определено содержание цинка, меди, свинца, кадмия и ртути в образцах шампуней, представленных на рынке Республики Беларусь.=Applying stripping voltammetry method it was established that all 8 shampoos samples stud-ied contained zinc (6,8–13,9 mg/kg), copper (0,09–1,57 mg/ kg) and lead (0,22–0,54 mg/kg), and zinc contained in amounts greater than other heavy metals in tens and hundreds of times. Cadmium and mercury are found in shampoos of 3 out of 8 samples studied: 0,008–0,017 mg/kg and 0,02–0,39 mg/kg, respectively. The content of lead and mercury is 5—22 and 2,5—50 times as low as the permissible level, regulated by the Technical Regulations of the Customs Union RHR-009, respectively.
