摘要:

指出目前分析化学教科书中关于单色光带宽对Beer定律影响的叙述有误。综述了光度法发展史,说明早在1954年Broderson已经给出了正确的论述。

关键词: 光度分析, 光谱带宽, Beer定律

Abstract:

An incorrect description about the effects of the spectral bandwidth on photometry measurements is presented in domestic analytical chemistry textbooks.In this paper, a review of photometry development history was given to show that Broderson had clarified the effects of spectral bandwidth in 1954.

Key words: Photometry, Spectral bandwidth, Lambert-Beer law
