摘要
The formation of thioctic acid(TA) self assembled monolayer(SAM) on gold electrode was monitored in situ by using quartz crystal microbalance(QCM).The effects of temperature and concentration on the formation of SAM,and the stability of TA SAM on gold at different pHs were studied.The information related to the kinetics of SAM formation was given.The results obtained indicated that the kinetics of SAM formation was in compliance with the Langmuir adsorption equation quite well,and the SAM was stable in the pH range from 5.4 to 7.6.
