Abstract : An improvement for an anodic stripping voltammetry system for measuring the presence and concentration of trace metals in a seawater solution yields more representative readings. A combination electrode is fashioned from a porous polyethylene cylinder having a coaxial bore for receiving the flowing solution. A helically extending silver/silver chloride reference electrode is disposed on the outside of the cylinder and a platinum counter electrode is located in its bore. The porous polyethylene prevents chlorides from contaminating the reference electrode while the counter electrode drains off currents. Thus, more representative potential readings between a working electrode and the reference electrode are made as trace metals are stripped away into the circulating solution. (Author)
