An ICP-AES method was established to analyze the contents of 17 common and trace elements in Xue Teng, which are K, Ca, Mg, P, Sr, Fe, Mn, Zn, Cu, Co, Cr, Al, Ba, Ni, As, Pb and Cd. The samples were pretreated by microwave digestion method and the element contents for several kinds of Xue Teng were determined by ICP-AES. The result showed that the detection limits were in the range of 0.000 03~0.009 81 μg/mL and the recovery rates were in the range of 88.37%~110.00%. The precisions were less than 5.0%. The method is fast, sensitive and accurate and can be used to determine multiple common elements and trace elements in Xue Teng. The results show that in addition to three macroelements, K, Mg and Ca, five essential microelements, Fe, Zn, M n, Cr and Co, and eight other elements, P, Ni, Ba, Al, Sr, Pb, Cd and Ba were detected in Xue Teng. |
