[Determination of Al and ca in soil by laser micro-plasma spectroscopy].
Laser micro-spectral analyzer, coupled with CCD spectrometer, was used to determine soil elements in argon atmosphere at reduced pressure in the authors' experiment. The accuracy and availability of this method were studied. With Al I 394.40 nm and Ca II 396.85 nm as spectral analysis lines, using "the three standard samples method", the contents of Al and Ca in soil were determined. The results show that the maximum of relative standard deviation (RSD) of quantitative analysis is 5.80%; the maximum of relative difference between the quantitative analysis result and the standard value is 7.65%, suggesting that the accuracy of determination of Al and Ca in soil meets the challenge of quantitative analysis.
