【Abstract】 The adsorption equilibrium, adsorptionkinetics and mechanism of palladium from hydrochloric acid medium with quaternary ammonium salt N₂₆₃-silica as stationary phase were studied by means of extraction chromatography and atomic absorption spectrophotometry.Based on column test, the method for the separation and preconcentration of palladium with N₂₆₃-silica was established.更多还原
