UltravioletandVisibleAbsorptionSpectrometry UltravioletandVisibleSpectrophotometryUV-VIS 概述 通过测定分子对紫外-可见光的吸收对物质进行定性和定量分析。λ：190~750nm 一、紫外-可见吸收光谱 吸收光谱又称吸收曲线，是以入射光的波长λ 为横坐标，以吸光度A为纵坐标所绘制的A-λ曲线。最大吸收峰 1、有机...
ultraviolet-visible absorption spectrometryUltraviolet-visible absorption spectrometry is used for the determination of many inorganic,organic,and biological species. However,poor selectivity limits its applications for quantitative analysis in complex mixtures. In this work,its mathematical selectivity was ...
