| Abstract: | The method for the determination of copper,zinc,manganese,iron,magnesium,calcium in wild pine tea by microwave plasma torch-atomic emission spectrometry(MPT-AES) was developed.The effect of nitric acid concentration in the sample solution and co-ionized elements on the emission intensity of copper,zinc,manganese,iron,magnesium and calcium was investigated in detail.The experimental conditions were optimized and showed that the detection limits of metal Cu,Zn,Mn,Fe,Mg and Ca are 3.6,7.7,6.1,14.1,0.5 and 0.9 ng/mL,respectively,and the RSD of the method is between 1.05%～6.46%,the recoveries are 97.25%～103.37%.This demonstrated that the proposed method is simple,accuracy and efficient,providing a well-established analytical method. |
