【Abstract】 In this paper, the purification method of the reagent 8 hydroxyquinoline 5 sulphonic acid in silica column chromatography is reported. The effect of fixed adsorbent, developer and solvent on depuration product has been studied, the conditions are that silica gel acts as fixed adsorbent, 1 propanol (or 2 propanol) to aqueous ammonia is 2 to 1 as developer, and distilled water as solvent. The depuration product has been characterized by IR and HPLC, and the purity of the product is over 99%.更多还原
