【Abstract】 A method of direct determination of aluminum in drinking water by graphite furnace atomic absorption spectrometry was established. The ashing temperature was 1 500 ℃ and the atomization temperature was 2 400 ℃, without matrix modifier, ordinary graphite tube was used to directly determine aluminum in drinking water. The mass concentration of aluminum had a good linear relationship with the absorbance peak area in the range of 0-50 μg/L, the correlation coefficient was 0.999 1, and the detection limit of the method was 0.34 μg/L. The recovery rate of spiking was 106.4%-112.6%, and the relative standard deviation of the determination result of tap water sample was 0.62%(n=6). The direct determination of aluminum in drinking water by graphite furnace atomic absorption spectrometry is simple, rapid and less interference.更多还原
