DETERMINATION OF COPPER ZINC OF HUMAN HAIR BY SOLID SAMPLE INTRODUCING DIRECTLY

The method of the solid sample directly introducing the atomizer for determining the copper and zinc of man's hair is studied in this paper. With this method, we use coating Lanthanum inner mini-cup with Hitach 180-80 Zeeman Atomic Absorption Spectroscopy standard cup atomizer and predigestion. Overcomming long-time chemistry pretreatment, results are very satisfactory with optimum program conditions. This method has the advantages of accuracy and rapid and good repeatability. (relative standard deviation is about 5 precent).
