【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10.2 mg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20.0 cm,内径1.0 cm,内装2.5 g D311A树脂的吸附柱对流速为2.0 mL/min、浓度为20μg/mL的五氯苯酚钠(50 mL)吸附率可达98%。负载柱可用0.1 mol/L NaOH完全洗脱。更多还原

【Abstract】 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 Langmuir 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.更多还原
