| Abstract: | The calcium,magnesium,iron,zinc,copper,manganese in Du Qing Yao were determined by flame atomic absorption spectrometry with calibration curve method after the sample was digested by microwave with HNO3.The content of Ca was obtained as 9.07mg/g,Mg 3.56mg/g,Fe 2.11mg/g,Zn 0.070mg/g,Cu 0.022mg/g,Mn 0.61mg/g.The RSD of the method was in the range of 3.1%—9.6%,and recoveries in the range of 94%—105%.The method is accurate and satisfying. |
