Evaluation of Potential Eluants for Non-Acid Elution of Cesium from Spherical Resorcinol-Formaldehyde Resin
Ion exchange column loading and elution of cesium from spherical resorcinol-formaldehyde resin have been conducted for two potential non-acid eluants - (NH4)(2)CO3 and CH3COONH4. The results revealed encouraging cesium elution performance. Virtually complete cesium elution was achieved with 28 or less bed volumes. Elution performance was fairly high at similar to 8 bed volumes for some of the eluants and also practically comparable to the benchmark acid eluant (HNO3). Elution is generally enhanced by increasing the concentration and pH of the eluants, and combining the eluants.
