| 摘 要： | 在用空气—乙炔火焰原子吸收光谱法测定钢中镁时,在试液中加入一种阳离子型表面活性剂(十六烷基三甲基溴化铵),可以使镁的吸光度增加,从而利用这种增感效应降低了特征浓度,提高了分析灵敏度,即可简便、准确地测定样品中痕量的镁。

| Abstract: | When we detectc the content of magnesium by air-ethyryl flame atomic absorption spectrometry, adding some a-SAA cetyltrimethylammanium bromide to test solution, the absorbence is increased.By this enhancement effect the characteris -tic concentration is decreased and the sensitivity is increased, therefore the trace magnesium in sample can be simplely and conveniently and accurately detected. |
