摘要：

A low-power surface-wave plasma device (surfatron) is employed as an atomizer for microwave induced plasma atomic absorption spectrometry (MIP-AAS) and a desolvation-condensation apparatus has been used to remove the solvent in the aerosol. An axial viewing absorption technique is adopted for the determination of calcium. The matrix effect on its determination has been investigated in detail. Some enhancing effects are observed on the calcium absorbance in the presence of organic additives. A possible mechanism for this enhancement is discussed.
