摘要

The separation processes of ion exchange and sorption have been widely used for many years throughout the nuclear industry to decontaminate aqueous waste streams. The two processes are analogous, both removing ions from solution either by exchange of a counter ion (ion exchange) or by direct physical removal (sorption). Standard formulations of sorbents are used worldwide to treat waste streams, but as new materials are manufactured and discharge authorisations are lowered, it becomes increasingly difficult for operators t adhere to the governing principles of ALARP (as low as reasonably practicable) and BATNEEC (best available technology not entailing excessive cost). The objective of the Novel Absorber Evaluation Club is to remain aware of new sorbent developments and produce decontamination data on these products for direct comparison with standard 'benchmark' materials.
