| Abstract: |
| Objective: To establish a method for the determination of the 8 trace elements in cosmetics. Method: Y,SLi, In, Bi, was used to the internal standard solution．The samples were analyzed by inductively coupled plasma-mass spectroscopy, using microwave digestion for sample pretreatment. Results: The mass ratio of each measured element,the corresponding internal standard element and the concentration showed a good linear relationship in a certain concentration range,and the correlation coefficients were all greater than 0. 9998. The recoveries were from 95% to 104%,and Relative standard deviation were all less than 3%．Conclusion: The method is sensitive and accurate,and can be used for the limit determination of the above elements in cosmetics． |
