摘　　要：研究了D311A树脂对五氯苯酚钠的吸附性能。结果表明，pH控制在5—9范围内，D311A树脂对五氯苯酚钠有良好的吸附效果，最大静态吸附量为10．2mg五氯苯酚钠／g树脂。等温吸附符合Freundlich和Langmuir等温式，相关系数在0．99以上。柱长20．0cm，内径1．0cm，内装2．5gD311A树脂的吸附柱对流速为2．0mL/min、浓度为20μg／mL的五氯苯酚钠（50mL）吸附率可达98％。负载柱可用0．1mol／LNaOH完全洗脱。The adsorption properties of D311A resin for sodium pentachlorophenolate were studied in detail. The results show that control pH in 5 - 9, the D311A resin had a good adsorption to the sodium pentachlorophenolate. The static adsorption capacity was 10.2 mg/g dry resin. The adsorption isotherms approximately fit the Freundich an Langrnuir equation with a correlation coefficient larger than 0.99 in the range of experimental concentrations. With the length of the column was 20.0 cm, the diameter was 1.0 cm and had 2.5 g resin in it,the adsorption pole had 98% adsorption rate to 50 mL sodium pentachlorophenolate which velocity is 2.0 mL/min, concentration is 20 μg/mL. The adsorption pole can be eluted entirely by 0.1 mol/L sodium hydroxide.
