| Abstract: | The determination of manganese by MIP-AAS was studied systematically in this paper. The sample was introduced into the plasma by using an ultrasonic nebulizer and a desolvation system consisting of a heated tube,a watercooling condenser anda concentrated H_2SO_4 dessicator. Various experimental parameters. such as microwave forward power, carrier gas flow rate,acidity of sample soutions,were examined and compared for T-shaped and Lshaped discharge-absorption cells. The characteristic concentrations for manganese were shown to be 5ng/mL for T-shaped cell and 26ng/mL for L-Shaped cell. Marked enhancements in sensitivities for Mn was observed when Ca or La was added to the solutions. The method has been used to analyse practical soil samples, satisfactory results were obtained. |
