| Abstract: | lowpower
argon microwave induced plasma with an electrothermal vaporization sample introduction
system was used as an atomizer for AAS.A concentrated H2SO4 desiccator was used for
desolvation.Experimental parameters such as microwave forward power,carrier gas flow
rate,voltage of desolvation,time of desiccation ,voltage of vaporization and acidity of the
solution for determining trace Ag and Cd by AAS were optimized.The method has been
successfully applied to the analysis of aqueous samples. |
