摘要
本文介绍用双工作电极串联式的薄层电池,结合阳极溶出伏安法,用上游工作电极作富集-溶出电极;下游工作电极作收集电极,记录下游工作电极的收集电流。本法具有溶出法和薄层伏安法的优点,可消除电位扫描引入的电容电流,以及吸附电流、杂质电流的干扰,有效地提高了信噪比,提高了测定的灵敏度和分辨率。
A application of the analytical method of double working electrodes thin-layer electrolyticcell in series has been re ported in this paper.The first electrode in flow path is used for anodicstripping and riching,and the second electrode for collecting,and the reduction current of thesecond electrode is recorded, This method has the advantages of anodic stripping and poten-tiostat voltametry of thin-layer cell.
