Abstract

ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) analysis was applied to assess element concentrations in six samples of mineral supplements/multivitamins acquired in pharmacies from Romania. Concentrations of Fe, Ca, Mg, Zn, Li, Ba, Sr, Ni, Cu, Sn, Al, Co, Cr, Mn, Mo, Se, K, Na, Cd, Pb were determined. The digestion method with acid mixture (HNO3 an H2O2) was used to destroy the organic material. Generally, the Ca, Fe, K and Mg contents were normal to higher range compared to the labelled quantity. The Cu, Mn, Se, Ni, Sn and Zn contents were low in most of the formulations when compared to the labelled amounts. Li, Ba, Sr, Na, Al, Cr, Sr, Co were quantified in some formulations where they were not labelled, this may be due to the excipients that may have been used in the formulations. The concentration of the toxic elements Pb and Cd are within the allowed limits. Based on the results obtained in the present study, it is concluded that the present techniques are adequate for the routine determination of heavy metals concentration in mineral supplements.
