[Study on the determination of aluminum in soil samples by air-acetylene flame atomic absorption spectrometry].

This paper reported a method for the direct determination of aluminum in soil samples by air-acetylene flame atomic absorption spectrometry. The enhancement effect on aluminum of adding tetramethylammonium chloride was studied. 43 microg/mL/1% of characteristic concentration was reached. This method is simple, rapid and useful, and has been applied to the determination of aluminum in standard soil samples, and a good agreement was achieved.
