铝的空气-乙炔火焰原子吸收法测定的研究

Study on the Determination of Aluminum in Soil Samples by Air Acetylene Flame Atomic Absorption Spectrometry

本文建立了一种用空气－乙炔火焰原子吸收法直接测定土壤中铝的分析方法。研究了添加四甲基氯化铵（ＴＭＡＣ）对测定铝时的增感效果，方法简便，快速实用，应用于土壤标准样品的测定，获得满意的结果。

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 μg/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 samlpes,and a good agreement was achieved.
