近几年来发表的有关分光光度测定方面的著作增加很快。但是,由于对许多著作未作评论,因而通常对所提方法的优缺点并不清楚。用国际上对错误进行判断的统一标准和有约束力的参数来对测定一种元素的试剂和方法进行客观比较是不可能的。一个分析工作者要从一大批所供应的试剂内挑选出对他的工作适合的试剂,实际上就会遇到这些困难。为了消除误解,往往必须进行大量的费时的预先试验,以做出精确的判断。
The publications on spectrophotometry published in recent years have increased rapidly. However, since there have been no comments on many books, it is not clear what the pros and cons of the proposed method are. It is impossible to objectively compare reagents and methods for the determination of an element with uniform international standards for judging errors and binding parameters. An analyst who actually chooses a suitable reagent for his job from a large pool of supplied reagents actually encounters these difficulties. In order to eliminate misunderstandings, it is often necessary to carry out a large amount of time-consuming pre-trial to make accurate judgments.
