| Abstract: | Objective To develop a inductively coupled plasma mass spectrometry （ICP - MS） method for the determination of heavy metal element in the tung oil. Methods The samples were digested by nitric acid, hydrogen peroxide and perchloric acid, then the 12 heavy metal element in the tung oil were detected by ICP- MS. Results The limit of quantification （LOQ） were the range of 0. 000 8 ~0. 474 6μg/L for 12 elements, the recoveries were ranged from 88.9% - 108.0% , and the relative standard deviations were 0.3% -7.8%. Conclusion This method is simple, fast, accurate, and can be used to detect the heavy metal elements in tung oil. |
