| Abstract: | Determination of A1, Ca, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, Pb and Zn in hu- man hair by ICP-AES is studied. The recoveries are in the range of 90.5~ 100%, and the coefficents of variation less than 5% except Ni, K and Na. The results of comparison studies are satisfactory. The recommended method is simple, rapid. Only small sample (0.1g) is enough. |
