【Abstract】 A new type of self-made column packing of polyamide with certain particle size and better compressive strength is investigated. It shows a great adsorbing capacity, about 9～15 mg acidio and neutral dyes or 1～3 mg alkaline dyes to pass the column(0.8cm×5.0cm) with flow rate 5～10 ml/min, and the dyes could be adsorbed completly. The dyes adsorbed on the column could be eluted perfectly with alcohol containing some alkali solution (pH8～10). The recovery range is 70%～90%. The pure dyes eluted from the column could be determined by ultraviolet/visible, infrared and other spectroscopy. It couid be expected that a number of compounds can be enriched and separated in environmental water samples and pretreated in high-performance liquid chromatography samples and some natural plant components with the packing.更多还原
