若以 Beer 定律在1852年发表算起,光度法已有一百多年的历史。多少年来它是十分流行的一种分析方法,其成果也日新月异。但随着现代科学技术的不断发展和对分析法的要求日益提高,出现了不少新的分析法,光度法在各种方法中所佔地位近年似有下降趋势,但其发表的论文绝对数量仍然不少。那么它的前景怎样?如何发展?这是很多分析工作者所关心的问题。就此进行必要的讨论,将有助于正确地看待、合理地使用、有效地发展它。
If Beer’s Law was published in 1852, the photometry method has a history of over one hundred years. It has been a very popular analytical method for many years and its achievements are changing rapidly. However, with the continuous development of modern science and technology and the increasing demand for analytical methods, many new analytical methods have emerged. The position of spectrophotometry in various methods seems to be declining in recent years. However, the absolute number of papers published Still a lot So what is its outlook? How to develop? This is the concern of many analysts. The necessary discussion in this regard will help to correctly and properly use and effectively develop it.
