| Abstract: | A thin SiO_2 layer was prepared on the electrode surface of a quartz crystal microbalance(QCM).The(adsorbed) amounts of cationic polydiallyldimethylammonium chloride on the SiO_2 layer,as well as an anionic dye of actived red K-2BP on the pre-adsorbed polyelectrolyte film,were monitored real time during the initial adsorption processes.The influence of ionic strength and pH of the solution on the adsorption of polyelectrolyte and dye was investigated.The QCM is a sensitive and simple method to simulate the processes related to flocculate and remove of dye by polyelectrolyte. |

| Keywords: | polyelectrolyte dye adsorption quartz crystal microbalance. |
