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.

Key words: tea infusion, trace element, Visual MINTEQ
