摘要：
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 0.30 pM and from 0.24 to 0.47 pM for total-iodine. Compared with those values in the open oceans, iodide was enriched in Osaka Bay, because of activities of marine organisms. While, totaliodine showed considerable uniform distribution.
