Abstract

In the present paper, a method was developed for the determination of Cd and Pb by ICP-AES. The effects of two different sample treatment methods, including wet digestion method and dry ash method, were compared. The contents of Cd and Pb in Danshen (Radix Salviae miltiorrhizae) grown in some areas of Shandong were determined. The results show that it is satisfactory to apply ICP-AES to the determination of Cd and Pb with the detection limits (DL) of 1.92 ng x mL(-1) and 1.07 ng x mL(-1), the precision values (RSD) of 3.14% and 1.83%, and the recovery rates of 103.0% and 96.2% respectively. The wet digestion method is better than the dry ash method for its lower RSD and higher recovery rate. The dry ash method is suitable for the determination of Pb, but not suitable for the determination of Cd due to its low recovery rate. The results also show that the contents of Cd and Pb in Danshen are lower than the standard of Chinese Pharmacopoeia (2005), which meets the standard of GAP production.
