摘要
使用热浸涂法和粉压法制备了工程用Ag/AgCl参比电极。电化学性能测试表明热浸涂法和粉压法制备的Ag/AgCl参比电极的电位稳定性都比较好,但热浸涂法制备的Ag/AgCl参比电极的耐极化性能优于粉压法制备的Ag/AgCl参比电极。热浸涂法和粉压法制备的Ag/AgCl参比电极的温度系数都比较小,温度响应特性较好。海水流速对热浸涂法和粉压法制备的Ag/AgCl参比电极的电位有明显影响,参比电极封装外壳可改善电极在流动海水中的电位稳定性能。
Ag/AgCl reference electrodes for engineering were prepared with powder press and thermal dip-coating method.The electrochemical test result showed that the potential stability of them were both good;the Ag/AgCl reference electrode prepared with thermal dip-coating method has smaller polarization resistance than the one prepared with powder press method;the temperature coefficient of Ag/AgCl reference electrodes prepared with thermal dip-coating and powder press method are both small.It showed that the relative flow velocity of seawater has obvious effect on the electrode potential;encapsulation of reference electrodes can improve their potential stability in flowing seawater.
