Use of Strong Base Organic Anion Exchangers for the Removal of Suspended Alumina Particles in Light Water/Heavy Water Systems

Abstract

A method for the removal of suspended alumina particles from H₂O/D₂O systems has been developed. It is based on the modification of surface charge of the suspended hydrated alumina particles by the addition of sulfate ions and adsorbing them on conventional strong base anion exchanger. 48 ppm of added sulfate has been found to be the required concentration for treating 30 ppm Al₂O_{3 3}D₂O suspensions.
