【 摘 要 】

Tea infusion is one of the most popular drinks around the world. Since tea infusion is known to contain several essential nutrients, it is considered a healthy beverage. In this study eight different Iranian brands of tea infusion and eleven brands imported tea infusion samples from another country for Cu, Zn, Mn and Al were determined by flame atomic absorption spectrometry after wet digestion. The results of analysis showed that the extraction rates of minerals from dry black tea to infusion tea were for Mn (19.35%), Cu (22.75%), Zn (54.43%) and Al (61.48%). The results obtained from this analysis have shown good accuracy.
