研制了一种新型离子色谱安培检测器电解池。电解池为三电极体系 ,由工作电极 (Ag电极 )、辅助电极 (Pt电极 )和参比电极 (Ag/AgCl电极 )组成。工作电极采用柱状电极 ,电极均用螺纹接头固定在电解池上。新型电极池具有工作电极表面积大 ,拆卸清洗方便等优点。应用装有新型电解池的离子色谱安培检测器测定了Br-、I-、SCN-,检测限分别为 16 μmol/L、8μmol/L和 2 0 μmol/L。An electrolysis cell used on amperometric detector was designed. It is a three-electrode system, comprising working electrode (Ag electrode), auxilliary electrode (Pt electrode) and reference electrode (Ag/AgCl electrode). The working electrode was fabricated with the form of a rod and has large surface area. Three electrodes are fixed in the cell by screw joints so they are easy for dismantling and cleaing. The Br -, I - and SCN - has been determined by ion chromatography with the new detector, and the detection limits are 10, 8 and 20μmol/L, respectively.福建省科技项目 (2 0 0 1H0 81) ;; 厦门市科技计划项目 (3 5 0 2Z2 0 0 12 5 1
