摘　　要：研究了HDX-8树脂对2，4-二氯苯酚的吸附性能。结果表明，静态条件下在pH2～6范围内，对2，4-二氯苯酚具有良好的吸附性能，最大静态吸附量为9．725mg2，4-二氯苯酚／g树脂。等温吸附符合Freundlich和Langmuir方程式，相关系数均在0．99以上；柱长8cm，内径1．0cm，内装2．5gHDX-8树脂的吸附柱对流速为5mL／min，浓度为20μg／mL的2，4-二氯苯酚溶液的吸附率达到99％；负载柱可用1mol／mL的NaOH洗脱。The adsorption properties of HDX-8 resin for 2,4-dichlorophenol were studied in detail. The resuits show the static adsorption capacity was 9. 725 mg/g dry resin at pH 2 - 6. The adsorption isotherms approximately fit the Freundlich and Langmuir equation with a correlation coefficient larger than 0.99 in the range of experimental concentrations. When the concentration of 20 g/mL of 2,4-dichlorophenol, in the flow rate of 5 mL,/min, length of column 8 cm, diameter 1.0 cm, the contents 2.5 g HDX-8 resin col- umn,the absorption rate is 99%. Column packed with HDX-8 resin can be eluted with 1 mol/mL NaOH.
