Abstract

Iodide- and total-iodine (Iodide+iodate) in seawaters of Osaka Bay were determined by an electrolytic concentration on glassy carbon electrode and detection with a polished Ag3SI electrode. The standard deviation of this method was within about 2% The concentrations of iodide-iodine in seawaters of Osaka Bay were in the range from 0.10 to 0.30μM and from 0.24 to 0.47μM for total-iodine. Compared with those values in the open oceans, iodide was enriched in Osaka Bay, because of activities of marine organisms. While, total-iodine showed considerable uniform distribution.
