Determination of Sulfadiazine Based on Its Derivatization with Fluorescamine by Self-Ordered Ring Fluorescence Microscopic Imaging Technique
SOR Sulfadiazine Fluorescamine Derivatization
2012/8/31
A self-ordered ring (SOR) fluorescence microscopic imaging technique has been developed for the determination of trace amounts of sulfadiazine based on its derivatization with fluorescamine. In the pr...
基于差分吸收光谱算法，使用卫星数据反演大气NO2和SO2等痕量气体柱浓度的时候，Ring效应是影响反演结果精度的一个重要因素。Ring效应是指：受太阳表面大气消光效应影响，产生称之为夫琅禾费线的暗线结构，而由于太阳光在地球大气中传输引起非弹性散射，导致观测到的夫琅禾费线变短，这个结果可以近似地认为是对夫琅禾费线的填充。研究表明，大气中的N2和O2分子的转动拉曼散射是导致Ring效应的主要原因。利用...
基于散射光、利用痕量气体指纹吸收特性反演气体浓度的方法称为被动差分吸收光谱法(passive DOAS)。因其具体结构简单，易于平台搭载等优点近年来获得了长足发展。被动DOAS中利用太阳散射光作为光源解析大气污染气体柱浓度时，会受到太阳弗朗和费光谱的“填充线”即Ring效应的强烈影响，尤其是对浓度很低的痕量气体，致使不易获取其浓度、影响其测量精度。文章以反演大气中NO2气体为例，介绍了稳定天气条件...
