Abstract

In order to develop radiation resistant membranes for the treatment of high level waste (HLW), ceramic tubular membranes were prepared by incorporating varying amounts of ammonium molybdophosphate (AMP), known for efficient Cs(I) uptake from acidic feeds, for the recovery of radio-caesium. The sorption of Cs(I) onto the membrane increased linearly with increasing the AMP content (10%-40%). Radiation stability of the membranes was evaluated by exposing them to gamma radiation obtained from a(60)Co source. The composite ceramic material showed excellent radiation stability without any morphological change up to 1100 kGy, indicating its potential application in radioactive waste treatment. For 10% AMP loaded ceramic membrane, the Cs(I) sorption decreased linearly with radiation dose. However, Cs sorption was not altered up to 1100 kGy dose for 20% and 40% loaded AMP.
