| Abstract: | After decomposition of Tibetan pharmaceuticals by either dry ashing method or wet digestion method, cadmium in Tibetan pharmaceuticals was determined by graphite furnace atomic absorption spectrometry. The results indicated that the method is simple, rapid and accurate with pretreating and determinating by wet digestion method. The extraction recoveries were between 95.0% and 103.0% with relative standard deviations of less than 1%. |
