Create ferrocyanide composite vinyl polymer and of the polymer as well as the cesium ion adsorbent containing the polymer

摘要

PROBLEM TO BE SOLVED: To provide a product capable of adsorbing cesium ions in water with rapidity and excellent in handling, with consideration of the present state of prior art that ferrocyanide such as Prussian blue is expected to be used as a treatment agent for a radioactive waste liquid as it is excellent in cesium ion selectively even under environment with various metal ions such as in sea water, and to solve the problem in handling such as taking time for recovery after use or dispersion because it is a powder, and also its cesium ion adsorption rate is not always satisfactory when followed a proposal to be carried on zeolite.;SOLUTION: There is provided a ferrocyanide conjugated vinyl polymer containing ferrocyanide of 0.1 to 5.0 wt.% based on the vinyl polymer having 1 to 10 mmol/g of carboxyl group and a crosslinked structure.;COPYRIGHT: (C)2014,JPO&INPIT
