Use of NiS coprecipitation was found to be very effective at a concentration level of 2500ppm of Ni+2 and 1300ppm of S-2 for the effective removal of 106Ru from the effluent stream. However, the NiS precipitate increases the sludge volume. Efforts were made to form the composite material of NiS in combination with Poly methyl metha acrylate (PMMA) polymer beads. The NiS-PMMA composite beads were loaded in a column and its ruthenium uptake behavior was studied. The NiS-PMMA beads were found to be functioning satisfactorily in alkaline conditions. It has shown a Kd value of about 8000-9000. The NiS-PMMA composite material has also shown the potential for the uptake of 125Sb. The effect of salt concentration on the Kd value is negligible. The equilibrium conditions are achieved in around 25-30min in batch mode of operation. The composite material can be suitably used in the column mode of operation.
