摘要：

This paper describes an improvement of detection capability for microwave-induced plasma atomic absorption spectrometry (MIP-AAS) by using a modified desolation system, which includes heated tubing, a water-cooled condenser and a concentrated sulfuric acid desiccator. The influence of heating temperature, carrier-gas flow rate and microwave power on the analytical performance of MIP-AAS has been examined and the relationship between these experimental parameters discussed. The desolation efficiencies of the different steps, such as in the water-cooling system and sulfuric acid desiccator, have been quantitatively measured using silica gel traps. Under the optimized experimental conditions, an overall desolation efficiency of as high as 99% is achieved by using this recommended desolation system. The analytical figures of merit for MIP-AAS are compared and evaluated under different desolation conditions.
