| Abstract: | This article is aimed to provide a method for the simultaneous analysis of five heavy metals, including Cu, As, Pb, Cd, and Hg, in Chuanxiong Rhizoma and Gastrodiae Rhizoma through ICP-MS. Five heavy metals were determined by an inductively coupled plasma-mass spectrometry method after microwave-assisted digestion. The linear correlation coefficients were all better than 0.999. The lowest limits of quantification for all target elements were 0.003?0.134 ug·L-1, while the recovery values ranged from 80.04%?118.34%. This method was accurate, convenient, rapid, and highly sensitive, and can be applied to determine five heavy metals, including Cu, As, Pb, Cd, and Hg in Chuanxiong Rhizoma and Gastrodiae Rhizoma. |
