X-ray diffraction(XRD) showed that ZS could be well dispersed on the support until the loading was higher than 40%. N2<\/sub> adsorption-desorption and small-angle XRD were used to characterize the mesostructure of the samples. It was found that the hexagonal order and regular mesopores with unchanged pore size of SBA-15 were mostly retained after ZS incorporation; however,the intensities of XRD peaks of SBA-15 declined,and the surface area and pore volume decreased as the ZS loading increased,suggesting the partial loss of ordered mesostructure due to the impregnation of acidic ZS solution. Acid strength of the catalyst was measured via<\/i> Hammett indicators. Excellent catalytic performances of these catalysts were observed in the esterifications of acetic acid with 2-ehoxyethanol and citric acid with n<\/i>-butanol,respectively. The selectivities to desired esters were 100%,and the conversions of both 2-ehoxyethanol and citric acid were as high as 98% under optimal loading level and reaction conditions. The dosages of catalyst,molar ratio of alcohol to acid in reaction mixture and catalyst recycle were also investigated. The activities were decreased slightly during each recycle owing to the solubilization and loss of ZS in water,but could be mostly retained after recycle for several run times.","articleNo":"20100811","authorCnList":["傅鹏远"," 杨春"],"authorEnList":["FU Peng-Yuan"," YANG Chun"],"authorList":["傅鹏远"," 杨春"],"authors":"傅鹏远, 杨春","authorsCn":"傅鹏远, 杨春","authorsEn":"FU Peng-Yuan, YANG Chun","categoryName":"研究论文","categoryNameCn":"研究论文","categoryNameEn":"","citation":"傅鹏远, 杨春.

The concentrations of rare earths were determined with UV-Vis spectrometry. The adsorption capacities of rare earths on MWCNTs treated with different modification methods were compared with each other. The experimental results indicate that MWCNTs modified with NaClO has the highest adsorption capacity of rare earths. As representitives,the adsorptions of samarium(Sm),gadolinium(Gd),and ytterbium(Yb) on MWCNTs modified with NaClO were investigated in detail. Effects of various parameters such as the rare earth concentration,pH value,ion strength,amount of MWCNTs,and experimental temperature were investigated. The adsorption of Sm,Gd and Yb onto MWCNTs modified with NaClO increased with pH value in a range of 2~7. However,the adsorption capacity of the three rare earths decreased with increasing solution ion strength and MWCNTs mass. The adsorption reactions of all the three rare earths on MWCNTs modified with NaClO were exothermic processes.

Furthermore, the adsorption data were fitted with Langmuir and Freundlich isotherm models,indicating that both the models can fit the adsorption of Sm,Gd, and Yb well.","articleNo":"20100815","authorCnList":["佟珊珊"," 石云峰"," 吕学举"," 宋乃忠"," 刘威"," 贾琼"," 周伟红"],"authorEnList":["TONG Shan-Shan"," SHI Yun-Feng"," LV Xue-Ju"," SONG Nai-Zhong"," LIU Wei"," JIA Qiong"," ZHOU Wei-Hong"],"authorList":["佟珊珊"," 石云峰"," 吕学举"," 宋乃忠"," 刘威"," 贾琼"," 周伟红"],"authors":"佟珊珊, 石云峰, 吕学举, 宋乃忠, 刘威, 贾琼, 周伟红","authorsCn":"佟珊珊, 石云峰, 吕学举, 宋乃忠, 刘威, 贾琼, 周伟红","authorsEn":"TONG Shan-Shan, SHI Yun-Feng, LV Xue-Ju, SONG Nai-Zhong, LIU Wei, JIA Qiong, ZHOU Wei-Hong","categoryName":"研究论文","categoryNameCn":"研究论文","categoryNameEn":"","citation":"佟珊珊, 石云峰, 吕学举, 宋乃忠, 刘威, 贾琼, 周伟红. 多壁碳纳米管对稀土元素的吸附性能. 应用化学, 2010, 27(8): 944-949. doi: 10.3724/SP.J.1095.2010.90755.","citationCn":"佟珊珊, 石云峰, 吕学举, 宋乃忠, 刘威, 贾琼, 周伟红. 多壁碳纳米管对稀土元素的吸附性能. 应用化学, 2010, 27(8): 944-949. doi: 10.3724/SP.J.1095.2010.90755.","citationEn":"佟珊珊, 石云峰, 吕学举, 宋乃忠, 刘威, 贾琼, 周伟红.
