文摘

New biosorbents for cesium ion removal were developed from forestry residue. Combination of nickel hexacyanoferrate impregnation and TEMPO oxidation was tested. TEMPO oxidation improved nickel hexacyanoferrate impregnation. Bark sorption capacity was increased by a factor of 7 thanks to a synergistic effect. Stability of nickel hexacyanoferrate crystals during cesium adsorption was studied.
