摘要：
A novel p-acetaminophen resin (named as GQ-1) was synthesized with chloromethylated polystyrene and p-acetaminophen. It can be used without any wetting process. The objective of this work was to study the adsorption performances for vanillin onto GQ-1 with two kinds of the hydrogen bond site of acetamino group and hydroxyl group. The results showed that the adsorption property of vanillin onto GQ-1 was superior to XAD-4, H103, NDA150, and NDA88. The adsorption capacity of vanillin onto GQ-1 is not greatly discrepant until the solution pH is higher than 5.31. The saturated adsorption quantity of vanillin was up to 141.32 mg/mL (wet resin) according to the dynamic adsorption and desorption experiments at 293 K. The resin could be regenerated by 7 BV ethanol. © 2011 Gu Qing Xiao.

摘要：
Cerium and nitrogen co-doped TiO<inf>2</inf> nanocrystals were synthesized by a simple sol-gel process, using tetrabutyl titanate as the raw materials with (NH<inf>4</inf>)<inf>2</inf>Ce(SO<inf>4</inf>)<inf>3</inf> and urea as ion donors. The co-doped TiO<inf>2</inf> nanoparticles were characterized by X-ray diffraction and transmission electro microscopy. The photodegradation of glyphosate has been investigated in aqueous suspensions of doped TiO<inf>2</inf> under visible irradiation. The results exhibit a higher thermal stability of anatase than pure TiO<inf>2</inf>. The uniform test results show the optimal conditions: n<inf>Ce</inf>/n<inf>Ti</inf> n<inf>N</inf>/n<inf>Ti</inf> and calcining temperature was 0.08, 0.01 and 800°C. The highest degradation rate for co-doped TiO<inf>2</inf> show five times photocatalytic activity of Degussa P25. ©(2012) Trans Tech Publications.

摘要：
A novel water-compatible hypercrosslinked resin modified by p-aminophenol was synthesized with chloromethylated polystyrene and p-aminophenol by Friedel-Crafts reaction. The objective of this work was to study the adsorption performances for salicylic acid onto p-aminophenol resin. The results showed that the adsorption capacity of salicylic acid onto p-aminophenol resin was superior to XAD-4 resin. It is seen that the maximum adsorption capacity is observed at pH of 3.0. It was found the adsorption dynamics obeyed the pseudo-first-order rate equation and the intra-particle diffusion was the rate-limiting step. The maximum adsorption capacity of salicylic acid for p-aminophenol resin was measured to be 283.7 mg/g with the equilibrium concentration at 404.6mg/L. The micropore structure, the pore diameter of p-aminophenol resin, the hydrogen bond between p-aminophenol resin and salicylic acid bring the larger adsorption capacity.

摘要：
The macroporous polydivinylbenzene/poly(methyl acrylate) interpenetrating polymer network (PDVB/PMA IPN) was prepared by the sequential suspension polymerization method, and was modified to be hydrophobic-hydrophilic macroporous polydivinylbenzene/poly (sodium acrylate) IPN (PDVB/PNaA IPN) by converting the PMA to PNaA under the condition of base. The effects of different mass ratio of the two networks and different cross-linking degree of the second network on the pore structure and adsorption capacity of PDVB/PNaA IPN resin were studied. The PDVB/PNaA IPN resin whose adsorption quantity is the biggest was chosen to study further. The pore structure, the weak acid exchange capacity, the water retention capacity, and the swelling ability of PDVB/PNaA IPN resin were measured. The study focused on the adsorption isotherms of berberine at different temperatures. Isosteric adsorption enthalpy, adsorption Gibbs free energies can be calculated according to tSh1ermodynamic functions. The results show that the saturated adsorption quantity of berberine is up to 109.4 mg ml<sup>-1</sup> (wet resin) by the way of dynamic adsorption and desorption experiment. The resin could be reused by the mixture with 0.5% sodium chloride and 80% ethanol. On the one hand the hydrophobic PDVB in the PDVB/PNaA IPN resin has the ability of adsorption using π-πinteraction, and on the other hand the hydrophilic PNaA in the PDVB/PNaA IPN resin has the ability of adsorption using ion exchange interaction. An important conclusion can be drawn that the PDVB/PNaA IPN resin has a promising application prospect in extracting and separating quaternary ammonium type alkaloids such as berberine. ©2009 John Wiley &Sons, Ltd.
