摘要
介绍了一种简易的电化学石英晶体微天平(EQCM)自动记录电路,可利用常用的X—Y记录仪,在原位条件下同时记录电极上的质量变化和电信号变化。用铜的恒电流电沉积验证了EQCM的质量灵敏度,结果符合Sauerbrey方程。仪器已初步用于镍电极对1,4-丁炔二醇吸附的观察。
A simple recording circuit of electrochemical quartz crystal microbalance (EQCM) is reported. The variations of mass and chemical signals on electrode can be automatically recorded simultaneously using a common x-y recorder. The constant-current electrodeposite of copper was performed for verifying the mass accuracy of EQCM and the result is in accordance with Sauerbrey equation. The apparatus has been applied to the observation of adsorption of 1,4-butynedioi on nickel electrode.
