吸附是表面活性剂的一个重要特征.迄今用于原位监测表面活性剂在固体表面上吸附重量变化的方法尚不多见.近年来压电石英晶体作为一种高灵敏的质量传感器(石英晶体微天平)已被用于大气和溶液中多种微量成分的监测.用石英晶体微天平研究I~-、Br~-和表面活性剂在金电极上的吸附行为亦有报道.本文研究了十六烷基三甲基溴化铵(CTAB)、十二烷基磺酸钠(SDSO)、十二烷基硫酸钠(SDS)在银固态表面上的吸附平衡动力学特性及其吸附机制.
Adsorption is one of the most important characteristics of surfactant, so far there are few methods for in situ monitoring surfactant adsorption on the surface of the weight change weight method.In recent years piezoelectric quartz crystal as a highly sensitive mass sensor (quartz crystal Microbalance) has been used for the monitoring of many trace elements in the air and solution.It is reported that the adsorption behavior of I ~ -, Br ~ - and surfactant on the gold electrode by using quartz crystal microbalance has also been reported.In this paper, Adsorption Equilibrium Kinetics and Adsorption Mechanism of CTAB, SDSO and SDS on Silver Solid Surface.
