| 4 | CONDUCTIVITY METHOD APPLIED TO THE STUDY OFINTERACTION BETWEEN ADSORBENT AND ADSORBATE Ⅰ. ADSORPTION OF LOW CONCENTRATION OF FREE ACID BY REGENERABLE CHITIN显示文摘The adsorption of low concentration of free acid by regenerable chitin is followed by electric conductance determination. The effect of acid concentration, content of functional amino groups, and ionic strength on adsorption was discussed. Experimental results indicate that the active centre of regenerable chitin is the free amino groups on its surface, and that the rate of adsorption of free acid was found to be affected by two factors: the interaction between the adsorbent and the adsorbate in solution and that between the adsorbate molecules or ions in solution. | Chen Bingren He Guangping Ling Moyu Wang Ruixiang Chen Wensen (Department of Chemistry, South China Normal University, Guangzhou, 510631) | 1997 | Chinese Journal of Reactive Polymers1997，6，1： | 7 |
| 5 | ADSORPTION OF DINITROPHENOLS ONTO POLYMERIC ADSORBENTS AND ITS MECHANISM显示文摘The adsorption of 2,4-dinitrophenol and 2.6-dinitrophenol on non-polar and polar adsorbents was studied. The results showed that the equilibrium adsorption did not comply with the Langmuir equation and was not mono-layer absorption. It is of interest to notice that the effect of pH on the adsorption of 2.4-or 2,6-dinitrophenol onto ADS-7 and ADS-21 was very small. The result is explained by hydrogen bonding interaction between 2, 4- or 2. 6-dinitrophenol and the adsorbent ADS21. The large adsorption capacity of dinitrophenol onto ADS-21, which was about 500 mg/g at an equilibrium concentration of 400 mg/L. and the small dinitrophenol leakage in the effluent from ADS- 21 column presented a good prospect for treatment of wastewater containing dinitrophenol with absorbent ADS-21. | SHIZuoqing XUMancai 等 | 2000 | Chinese Journal of Reactive Polymers2000，9，1： | 7 |

| 7 | WATER-BLOWN POLYURETHANE RIGID FOAMS MODIFIED BY CHEMICAL PLASTICATION显示文摘Water-blown polyurethane rigid foams are getting more and more attention,because the traditional blowing agent HCFC141b has already been abolished to prevent the ozone layer from destruction.However,the polyurethane rigid foams blown by water have serious defects,i.e.friability and resulting lower adhesion strength.Thus,the purpose of this study is to resolve the problems by chemical plastication.The maleate was added to polyol-premix containing water or to polyisocyanate,with both of which maleate does not react.To prove the reaction when polyol-premix and polyisocyanate were mixed,the model composite was synthesized and analyzed by IR,NMR and ESI(MS).Furthermore,a series of water-blown polyurethane rigid foams added different amount maleate were successfully prepared.By testing impact strength and adhesion strength of the foams,the actual effect of adding maleate was obtained. | YU Ming XU Qiang | 2006 | Chinese Journal of Reactive Polymers2006，15，1： | 6 |

| 12 | ADSORPTION OF TANNIN FROM AQUEOUS SOLUTION ONTO MACROPOROUS CROSSLINKED POLY(N-VINYL-ACETAMIDE) VIA HYDROGEN BONDING显示文摘A strongly hydrophilic hydrogen-bonding adsorbent-macroporous crosslinked poly(N- vinyl-acetamide). which contain both hydrogen bond acceptor and donator, was synthesized. Adsorption mechanism and dynamic adsorption of tannin from aqueous solution onto the adsorbent were investigated. Most of the differential adsorption heats for various adsorption capacities calculated from the adsorption isotherms according to Clapeyron-Clausius equation lay in the range of hydrogen bond energy (8-50kJ/mol). Adsorption properties of the adsorbent were studied in detail. These results revealed a hydrogen bonding mechanism of the adsorption of tannin from aqueous solution onto the adsorbent. The result of the dynamic adsorption of tanning with the initial concentration under 600 mg/L showed that the adsorption rate of tannin exceeded 90% when the flow rate was 3BV/h and the effluent volume reached 100 BV. Therefore, the developed hydrogen-bonding adsorbent--macroporous crosslinked poly(N-vinyl-acetamide)—is an excellent adsorbent to remove tannin from extract of natural products. and has great value in application. | XUMancai XUMingcheng 等 | 2000 | Chinese Journal of Reactive Polymers2000，9，1： | 5 |
