Elemental Analysis of Medicinal Herbs and Dietary Supplements

Selected plants used in Traditional Chinese Medicine (Garcinia cambogia, Emblica officinalis, Angelica sinensis, Schisandra sinensis, Scutellaria baicalensis, Salvia miltiorrhiza, and Ocimum sanctum), European herbs (Echinacea purpurea, Cichorium intybus, and Vitis vinifera), and supplements derived from these products were analyzed for their macroelements (K, Na, Ca, and Mg) and microelements (Zn, Cu, Cr, Se, Mn, Mo, and Fe) concentrations by wavelength-dispersion x-ray fluorescence (WD-XRF), scanning electron microscopy–energy dispersive x-ray spectrometry (SEM–EDX), ion chromatography (IC), and inductively coupled plasma–mass spectrometry (ICP–MS). In addition, relevant aspects of heavy metal toxicity are discussed.

ANALIZA FIZYKOCHEMICZNA ODPADU Z INSTALACJI ODSIARCZANIA SPALIN METODĄ PÓŁSUCHĄ Z ELEKTROCIEPŁOWNI PRZEMYSŁOWEJ W JANIKOWIE

The paper presents results of the analysis of waste from semi-dry flue gas desulphurisation installation called Integrated Novel Desulphurisation (NID). A comprehensive analysis of the physicochemical properties was conducted, including analyzes of the content of ions SO 3 2and SO 4 2- (relating to 2CaSO 3 ·H 2 O i CaSO 4 ·2H 2 O), moisture, SiO 2 and R 2 O 3 and SEM-EDX analysis. The original method for the determination of sulphates (IV) using a potentiometric
