在分光光度法领域中,双波长和导数分光光度法在提高方法灵敏度和精密度、消除混浊背景和同时测定互有干扰的多元素方面颇具特色而令人瞩目,其在无机分析中的应用已有介绍和评述。近年来,特别是国内对于双波长和导数分光光度法在稀土分析中的应用研究十分活跃,进展迅速,在许多方面有新的突破。本文拟就这方面的情况作一简要评述。由于发表的文献较多,限于篇
In the field of spectrophotometry, dual-wavelength and derivative spectrophotometry are notable for their sensitivity and precision in terms of method sensitivity, the elimination of turbid backgrounds and the simultaneous determination of multiple elements that interfere with each other, and their use in inorganic analysis has been Have introduced and commented. In recent years, especially the application of dual-wavelength and derivative spectrophotometry in the analysis of rare earth is very active, rapid progress and new breakthrough in many aspects. This article intends to make a brief comment on this situation. Due to the published literature more limited articles
