摘　　要：研究了磁性碳纳米管对酸性品红的吸附特性,考察了吸附剂用量、吸附时间、酸性品红浓度、温度、pH值等因素对脱色效果的影响,探究了其吸附动力学和吸附热力学。结果表明:磁性碳纳米管对酸性品红的吸附符合准二级动力学模型。不同温度下磁性碳纳米管对酸性品红的吸附等温线可以用Langmuir方程及D-R模型进行描述。The adsorptive property of acid fuchsin on magnetic carbon nanotubes was studied. The effects of adsorbent dosage, adsorption time, initial dye concentration, temperature and pH on the adsorption efficiency were investigated. Adsorption kinetics and adsorption iso- therm were researched. The resultant kinetic data were well fitted by a pseudo-second-order model, the correlation coefficient R2 was 0. 99. The adsorption isotherms for acid fuchsin could be suitably described by the Langmiur isotherm model and D-R isotherm model.
