摘要
笔者采用石英晶体微天平实时监测离子液体溴代-1-甲基-3-正已辛基咪唑在石英表面的吸附过程．结果表明，该吸附过程可逆，其吸附等温线符合Langmuir方程，吸附动力学过程符合一级动力学模型，在pH=8．5时吸附平衡常数最大．研究离子液体在固／液界面的吸附特性，有助于了解其迁移行为，有利于水体净化处理．
The adsorption of an ionic liquid of 1 surface was monitored in real time by a quartz crystal -hexyl -3 -methylimidazolium from solution on quartz microbalance sensor. It was shown that the adsorption is reversible and the adsorption isotherm is in accordance with Langmuir equation. The adsorption kinetics follows the first - order kinetic model. The equilibrium constant has the maximum in solution of pH = 8.5. The adsorption of ionic liquid on the solid/liquid interface is helpful to investigate the transfer and removal characteristics of an ionic liquid in a solution.
