| Abstract: | The method was established for the determination of five trace elements including Ca,Fe,Cu,Zn and Pb in human hair by inductively coupled plasma optical emission spectrometry（ICP-OES）. The optimal analysis spectral lines were selected and the standard curves were established for every element in this method,the correlation coefficients r were larger than 0. 999. The method had low detection limits,and the recoveries of the elements were in the range of 94. 6% - 103. 1% . The method had good precision and the RSD（n = 5）in the range of 0. 65%- 1. 52% . The accuracy of the method was confirmed by the analysis of certified standard reference materials and the results showed the proposed method was accurate and reliable. |
