摘要
实验测定了溴代烷基三甲胺的吸附对单分散聚苯乙烯胶乳电泳速度的影响.在Stern双电层模型的基础上,从电泳数据求得了吸附等温线,改进了计算吸附位数与吸附自由能的方法,并讨论了可能的吸附机构.
The effects of adsorption of alkyltrimethyl ammonium bromides on the electrophoretic mobility of a monodisperse polystyrene latex have been examined experimentally.The adsorption isotherms were obtained from the electrophoretic date in terms of Stern electrical double layer model.An improved method was proposed for evaluating the number of adsorption sites and free energy of adsorption,and the possible mechanism of adsorption was discussed.
