中文摘要：

药品与个人护理用品中的双氯芬酸钠在水体环境中不断富集,对生态系统造成了潜在威胁.研究了磁性阴离子交换树脂MIEX对双氯芬酸钠的吸附,考察了吸附过程的影响因素、动力学和热力学.结果表明,溶液中性、搅拌速度〉250r/min、反应时间≥90min、不含其他无机阴离子时,树脂吸附效率最高,对双氯芬酸钠的去除率可达96.1%.按Langmuir和Freundlich吸附等温方程拟合结果,可初步推算该吸附过程为吸热过程.

英文摘要：

Diclofenac sodium is a typical substance used for composition of pharmaceutical and personal care products （ PPCPs ） . The adsorption process of diclofenac sodium to magnetic ion exchange resin （MIEX） was investigated, and the influencing factors , kinetics and thermodynamics were studied. Results showed that the diclofenac sodium reduced 96.1% by reaction with MIEX, while the solution was neutral, stirring speed≥250 r/min, reaction time ≥90 min and other inorganic anions was absent. According to Langmuir and Freundlich isothermal adsorption equation fitting results, it could be preliminary calculated that the adsorption process was endothermic process.
