紫外吸收光谱及荧光光谱广泛应用于纯化合物检验及环境污染的监测等,我们应用这两种光谱对不同类型的水样进行了分析和研究。 一、分析方法 取经过滤呈无色透明的水样20毫升,置于100毫升锥形分液漏斗中,调节PH至4,加入5毫升正已烷萃取二次,合并有机相。对同一样品同时进行鉴外吸收光谱的和荧光光谱强度的测定. UV absorption spectroscopy and fluorescence spectroscopy are widely used in the testing of pure compounds and monitoring of environmental pollution. We apply these two kinds of spectra to analyze and study different types of water samples. First, the analytical method Take filtered colorless and transparent water sample 20 ml, placed in 100 ml conical separatory funnel, adjust PH to 4, add 5 ml of n-hexane extracted two times, the combined organic phase. Simultaneous extraneous absorption spectra and fluorescence intensity measurements were performed on the same sample.
