摘要:
Oolong tea from the Fujian Province is very popular at home and abroad, especially in Taiwan and Southeast Asia. In order to elucidate the possibilities to compensate the need state of people to essential elements by the national drink,a set of samples of oolong tea from the Fujian Province were analyzed by total reflection X-ray fluorescence (TXRF), a fairly new efficient method in the field of multielement analysis. After addition of a single internal standard element (e.g. gallium) to a solution of tea leaves digested by acid or to an acidified tea infusion, a portion of 5 μ1 was dried on a sample carrier and then analyzed by TXRF.
