| 2 | ADSORPTION OF LATERALLY INTERACTING 1-NAPHTHOL/1-NAPHTHYL-AMINE MIXTURES ON NONPOLAR SURFACES FROM AQUEOUS SOLUTIONS显示文摘The binary adsorption behavior of 1-naphthol/1-naphthylamine mixtures in water on nonpolar adsorbent Amberlite XAD4 was investigated at 293 K,303 K and 313 K,respectively.The experimental uptakes of 1-naphthol and l-naphthylamine in all binary-component systems of different molar ratios were obviously higher than the corresponding uptakes predicted by the extended Langmuir model,assuming no interaction between the adsorbed molecules of the two components.This phenomenon was attributed to the cooperative adsorption effect arising from the hydrogen bonding interaction between l-naphthol and l-napbthylamine molecules.A modified extended Langmuir model was proposed to describe the binary adsorption behavior by means of introducing a fitting parameter related with the cooperative adsorption effect of the adsorbates. | Wei-ming Zhang Jin-long Chen Qun Chen Ming-yang He Bing-cai Pan and Quan-xing Zhang a State Key Laboratory of Pollution Control and Resources Reuse,School of the Environment,Nanjing University,Nanjing 210093,China b Research Center for Engineering Technology of Organic Poison Control and Resources Reuse in Jiangsu Province,Nanjing 210038,China c Department of Chemical Engineering,Jiangsu Polytechnic,Changzhou 213016,China | 2006 | Chinese Journal of Polymer Science2006，24，1： | 1 |
| 3 | EFFECT OF WEAK INTERACTIONS ON PHENOL ADSORPTION FROM AQUEOUS SOLUTIONS BY AMINATED POLYMERIC ADSORBENTS显示文摘Adsorption behaviors of phenol from aqueous solutions have been investigated in batch systems at 303 K and 318 K respectively,using hypercrosslinked polymeric adsorbent(CHA111),aminated hypercrosslinked polymeric adsorbents (NDA101,NDA103,NDA105)and weakly basic polymeric adsorbent(D301)with a view to studying the effect of hydrogen bonding and Van der Waals interactions between adsorbate and the adsorbent.All adsorption isotherms can be well fitted by Langmuir and Freundlich equations.Compared with D301 driven by hydrogen bonding interaction only and CHA111 driven by Van der Waals interaction only,phenol adsorption on aminated adsorbents driven by both hydrogen bonding and Van der Waals interactions were apparently different,i.e.,negative effect for NDA105,positive effect for NDA101 and synergistic effect for NDA103.In this synergistic action,some weak interactions would contribute more or less to the adsorption than they work individually. | Wei-ming Zhang Jin-long Chen Ai-min Li Bing-cai Pan Qun Chen Ming-yang He and Quan-xing Zhang a State Key Laboratory of Pollution Control and Resources Reuse,School of the Environment,Nanjing University,Nanjing 210093,China b Research Center for Engineering Technology of Organic Poison Control and Resources Reuse in Jiangsu Province,Nanjing 210038,China c Department of Chemical Engineering,Jiangsu Polytechnic University,Changzhou 213016,China | 2006 | Chinese Journal of Polymer Science2006，24，1： | 0 |
