As a technology for removing α nuclide that elutes in the cooling water at fuel debris retrieval of the Fukushima Daiichi Nuclear Power Station, a batch type adsorption method which is adding powder adsorbent to the buffer tank of water treatment equipment was investigated. In this study, influence of coexistence components (sodium, calcium, magnesium) on the americium and europium adsorption amount of powder adsorbent (iron oxide) were obtained in test, and the adsorption mechanism and required adsorbent amount were investigated.
