Multielemental Analysis of Teas, Herbs and their Infusions by means of Total Reflection X-Ray Fluorescence Spectroscopy

• Abstract:

  In this work, total reflection X-ray fluorescence (TXRF) spectroscopy was used for the simultaneous multi-elemental determination of thirteen elements (K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr, Ba and Pb) in 38 tea and herb samples. Infusions were also prepared and analysed by TXRF in order to determine the solubility of each element. Principal component analysis (PCA) was applied by using the elemental concentration values for the differentiation purposes.
