| Abstract: | A self _ assembled tantalum coil atomiser for atomic absorption spectrometry is described. Pro_perties of the atomiser for the determination of Cd, Cu, Mn and Pb were studied using Ar as protecting gas. Under the selected experimental conditions, the characteristic mass concentrations for Cd, Cu, Mn and Pb are 0.7, 17 ,28 and 31 g/L, respectively. This method has been used to determine Cu and Mn in some practical samples with satisfactory results. The method is characterized by simplicity and low _ cost. |
