原子吸收分光光度法如此迅速地发展成为现代的重要分析方法,突出的原因之一是其选择性较好.当然,这并不表明该法不受干扰.相反,在某些场合下还存在着诸如光谱干扰、背景吸收、化学干扰以及其他物理因素的影响.只是与其他一些分析方法比较,该法的干扰因素较少,并且往往也较容易消除而已.因此,在大多数情况下该法的选择性是比较好的. 对于该法的一些干扰情况以及产生原因和消除方法,已有不少专著及论文进行了讨论和评述.与此同时,也有一些研究工作者 Atomic absorption spectrophotometry so quickly developed into an important modern analytical methods, one of the prominent reasons for its better selectivity, of course, this does not indicate that the method undisturbed on the contrary, there are still some occasions Such as spectral interference, background absorption, chemical interference and other physical factors, but only with a few other analysis methods, the interference of the law is less, and often easier to eliminate only.Therefore, in most cases the law Selectivity is better.For some of the interference of the law as well as the causes and elimination methods, many monographs and papers have been discussed and commented.At the same time, there are also some researchers
