Abstract

The Flame Atomic Absorption Spectrometry method was used in the determination of four trace amounts of tea infusion. The Ion Chromatography method was used in the determination of amounts of F-, Cl-, NO2-, Br-, NO3-, PO43- and SO42- in tea infusion. Moreover, Fe, Cu, Zn and Pb in the tea infusion were simulated by the software Visual MINTEQ. The results revealed that Fe(OH)2+, Cu2+, Zn2+ and Pb2+ were dominant species in the tea infusion.
