| Abstract: | Microwave digest technique in a closed vessel was used in decomposition of the essential oil for the subsequent determination of total Pb by HG-AFS. The experimental conditions of microwave digestion-hydride generation were optimized. The detection limit of the method was 0.25 μg·L~(-1) and the RSD was less than 5%. The recoveries obtained were 86.5%～100.5%. |
