The selective removal of cesium by phenolic ion-exchange resins from highly salted alkaline radioactive solutions was studied. The resins were synthesized by alkaline polycondensation of phenol, resorcinol, catechol, and resorcinol-catechol mixture with formaldehyde and characterized for their moisture regain, ion-exchange (H{sup +} {yields} Na{sup +}) capacity, and distribution coefficient (K{sub D}) for cesium. The effects of open and sealed curing of the polymers on their properties were studied. The effect of Na{sup +}, NaOH, and Cs{sup +} concentration on the uptake of cesium by resorcinol-formaldehyde resin was investigated, in particular. The chemical, thermal, and radiation stabilities of the polymers were also studied.
