研究了水对甲苯溶液中长链脂肪胺、醇和羧酸在金红石型TiO 2表面吸附的影响。结果发现，在湿吸附条件下的酸的化学吸附减少，胺的化学吸附保持相同的无水条件下，并没有化学吸附的醇在TiO 2上。利用短链表面活性剂类似物模型体系和蒸汽吸附模型体系研究了水存在下表面活性剂的吸附和解吸机理。(C)1999 Elsevier Science B.V.保留所有权利。
The influence of water on the adsorption of long-chain aliphatic amine, alcohol and carboxylic acid from toluene solutions on the surface of TiO2 (rutile) was investigated. It was found that under wet adsorption conditions the chemisorption of the acid is decreased, the chemisorption of the amine remains the same as under anhydrous conditions and there is no chemisorption of the alcohol on TiO2. The mechanism of the surfactant adsorption and desorption in the presence of water was studied using model systems with short-chain surfactant analogs and adsorption from vapors.
