A new anodic stripping voltammetry (ASV) using a microporous membrane electrode has been developed for the on-line monitoring of trace CuII in concentrated alkaline solutions. Microporous membrane electrodes were prepared by plating gold onto membrane filters made of polypropylene (PP). By SEM observations, it was confirmed that the membrane filter was modified by gold fine particles. The microporous membrane electrodes were set in a penetrated-type electrochemical flow-cell, and CuII was deposited while the sample solution passed through the electrode. The concentration of CuII was estimated with the anodic stripping peak currents. The calibration curve showed linearity within a range of 0 – 25 μg L−1 CuII in a 48% KOH solution. The proposed method will become a useful technique for an on-line monitoring system for trace CuII, which has been in urgent demand by the semiconductor manufacturing.
