As well-known, the Fukushima nuclear disaster is the largest nuclear disaster since the Chernobyl disaster of 1986, releasing an estimated 10 to 30% of the radiation of the Chernobyl accident. It was an energy accident, initiated primarily by the Tohoku earthquake on 11 March, 2011, and the damage caused by the tsunami produced equipment failures in boiling water reactor systems, which induced a loss-of-coolant accident followed with nuclear meltdowns and releases of radioactive materials. In this work, a monitoring sensor of Co2+ ions as a clue of the leakage from a boiling water nuclear reactor was developed and its analytical performance was studied. The sensor system was based on a drop-type chemiluminescence which showed the merits of fast analysis with ultrahigh sensitivity. In addition, it has advantages of small sample consumption and less matrix interference or environmental influence in quantitative measurement. In this work, the limit of detection for Co2+ was 41.39 ppt, obtained from calibration curve. The interference by Cu and Fe ions were studied systematically, considering chemical and electrical behavior of interfering ions.
