ABSTRACT
OBJECTIVE@#To establish the electricity plate digestion and inductively coupled plasma-mass spectrometry (ICP-MS) method for determination of 33 inorganic elements in human hair.@*METHODS@#Lithium (6Li), Germanium (72Ge), Yttrium (89Y), Indium (115In), and Terbium (159Tb) were used as internal standards. The electric heating board digestion in a mixture of nitric acid and hydrogen peroxide was used as the pre-treatment of the hair. Thirty-three inorganic elements in human hair were analyzed by ICP-MS method.@*RESULTS@#The detection limit of ICP-MS was 0.0001 microg/g(Th)-10.9 microg/g (Ca) and the limit of quantitation was 0.0005 microg/g (Th)-25 microg/g (Ca). The recovery rate of this method was 86%-113%. The RSD for the intra-day and inter-day were less than 9.2%. The method was not statistically different from microwave digestion method.@*CONCLUSION@#This method is highly efficient and accurate. It can be used for analysis of 33 inorganic elements in human hair.
