Fine crystals of ammonium tungstophosphate (AWP) exchanger having high selectivity toward Cs were encapsulated in the biopolymer matrices (calcium alginate, CaALG). The uptake of Cs in the AWP microcapsule was 80.2 and 80.0% for simulated high-level liquid waste solutions of nitric acid and hydrochloric acid, respectively. The biopolymer matrices, however, adsorbed slightly Ru, Zr, Mo, etc.
