摘要
本文采用离子交换富集，以镀Ａｌ２Ｏ３石英管作为捕集器，用火焰原子吸收光谱法测定水中的铜，获得了满意的结果。原子捕集法的灵敏度为常规ＡＡＳ法的１９２倍，总灵敏度提高７６４倍。
By ion exchange method concentrating copper(Ⅱ),silica tube plated by A l2O3 is used as atom trapper.The satisfactor results are obtall1ed for the trace copper in water by flame atomic absorption spectrometry.The sensitivity of atom trapping is l9 I tunes higher than that obtained by conventional AAS method.By ion exchange method,the total sensitivity increases to 7640 fold.
