Abstract: A microwave digestion procedure was developed for trace Pb in cigarette adhesive using microwave digestion system,and the amounts of these trace metallic element was determined by atomic absorption spectrometry after microwave digestion.The recovery of Pb was on the top of 97% with the RSD of 0.5%.The results showed that this method was rapid,simple,minimized environmental contamination and the samples are completely digested,the chemical reagents were economized during the sample preparation.The precision and accuracy are satisfactory.
