| 1 | 多壁碳纳米管去除稀溶液中双氯芬酸的研究(英文)显示文摘Modified multi-walled carbon nanotubes(MWCNTs) were used as adsorbents for removal of diclofenac. The reaction conditions were examined. Langmuir, Freundlich, Temkin, and Dubinin–Radushkevich isotherm models were applied to determine appropriate equilibrium expression. The results show that the experimental data fit the Freundlich equation well. Thermodynamic parameters show that the adsorption process is spontaneous and exothermic. The kinetic study indicates that the adsorption of diclofenac can be well described with the pseudo-second-order kinetic model and the process is controlled by multiple steps. | 胡翔 程昭 | 2015 | Chinese Journal of Chemical Engineering2015，23，9： | 3 |
| 2 | Diffusion-controlled Adsorption Kinetics of Surfactant at Air/Solution Interface显示文摘For the diffusion-controlled adsorption,the expression of dynamic surface adsorption(t)was obtained by solving the diffusion equation.Two cases,i.e.the short and long time limits,were mainly discussed in this paper.From the measured dynamic surface tension of aqueous surfactant sodium dodecyl sulfate(SDS) solutions at25 °C,the adsorption kinetics of SDS at air/solution interface was studied.It was proved that for both of the short and long time limits,the adsorption process of SDS was controlled by diffusion. | 刘俊吉 徐芸 孙红秀 | 2013 | Chinese Journal of Chemical Engineering2013，21，9： | 3 |

| 4 | 有机蒙脱土对单宁酸的吸附性能显示文摘利用十六烷基二甲基羟乙基溴化铵对钠基蒙脱土(MMT)进行离子交换改性,制得有机蒙脱土(OMMT),并通过FT-IR、XRD对MMT改性前后的结构进行表征。通过静态吸附试验,探究OMMT对单宁酸(TA)的吸附条件和吸附机理。结果表明,OMMT吸附TA对pH值有较大的依赖性,吸附最佳pH值在4.0左右;吸附平衡时间为6h,吸附动力学曲线符合准二级动力学模型;吸附等温线用Langmuir方程比Freundlich方程能更好地描述;在pH值为4.0、TA初始浓度为500 mg/L、温度为20℃时,最大吸附容量为181.6mg/g;热力学参数ΔG、ΔH均为负值表明吸附为自发的放热过程。在饱和吸附和解吸重复7次后,再生OMMT吸附容量下降不到20%。 | 周艳 张建平 罗学刚 林晓艳 许必军 | 2014 | 化工进展2014，33，7： | 2 |

| 6 | 一种新型的分子印迹磁性类Fenton催化剂对诺氟沙星的吸附和降解研究(英文)显示文摘In this study,a novel magnetically separable adsorbent,molecular imprinting magnetic γ-Fe_2O_3/crosslinked chitosan composites(MIPs),were prepared by a microemulsion process.Adsorption and Fenton-like oxidative degradation of a model pharmaceutical pollutant norfloxacin(NOR) by using MIPs were investigated.Various characterization methods were used to study the properties of MIPs,and it is suggested that the hydroxyl groups are the main adsorption sites for NOR.MIPs present better selective adsorption for NOR than its reference antibiotic sulfadiazine.The NOR adsorption data can be well fitted by Langmuir isotherm model and pseudosecond-order kinetic model.The optimum pH range for NOR adsorption is 7-10.In addition,the MIP-catalyzed Fenton-like system(MIPs/H_2O_2) exhibits remarkably faster removal rate for NOR than the case of γ-Fe_2O_3/H_2O_2.The result indicates that MIPs will be a good functional material in decontamination of pharmaceutical wastewaters since MIPs can be magnetically recycled after the treatment. | 黄明杰 周涛 吴晓晖 毛娟 | 2015 | Chinese Journal of Chemical Engineering2015，23，10： | 1 |
