A simple analytical method was developed for the determination of Cd in the treated wastewater arising from Advanced Liquid Processing System (ALPS) at the Fukushima-1 Nuclear Power Plant. Cadmium in the wastewater containing sea salt was effectively purified by an anion-exchange procedure. It was found that more than 97% of Cd were recovered by the present procedure from a sample solution of 2M HCl. Since a radioactivity standard solution of Cd was difficult to purchase from venders, beta-ray counting efficiency for Cd was estimated using 99Tc and 36Cl standard solutions. Minimum detectable activity was calculated to be 0.003 Bq mL. The present analytical method would be well suited for a rapid and simple determination of Cd in wastewater treated by ALPS.
