| Abstract: | According to the operating process of GB/T 17593.1-2006 Determination of Heavy Metals in Textiles - Part 1： Atomic Absorption Spectrophotometry, the seven heavy metals, such as Cu, Pb and Cr etc., were extracted in acid environment and detected by GTA. The ash temperature curves and atomise curves of three typical heavy metals were studied. The detection limit was 0.08-0.25pg, recovery rate 93-106.4%, and the RSD 1.0--4.2%. |
