N_(263)-亚硝基-R-盐萃取色谱法分离富集痕量钯

Separation and Concentration of Trace Amount of Palladium by Extraction Chromatography Using N_(263) and Nitroso-R-salt Mixture as Stationary Phase

本文介绍以N_(263)^-亚硝基-R-盐的混合物为固定相,以硅胶为载体,萃取色谱法分离富集痕量钯,并用2.5ml 1mol的HClO_4溶液淋洗钯-亚硝基-R-盐的铬合物直接进行比色测定痕量钯。

Using N_(263). and Nitroso-R-salt mixture as stationary phase and silica gel as support, traceamount of palladium has been separated and concentrated by extraction chromatography, Then thepalladium-NRS complex was eluted with 2.5 ml of 1 mol/1 HC_1O_4 and determined by spectro-photometry at 530 nm.
