Study of solid extractants based on malonamides, dyglicolamides, and pyridines for the partitioning of minor actinides from high active wastes
Original language description
In this work, the performance of the solid extractants with polyacrylonitrile (PAN) binding matrix was studied for the separation of lanthanides and actinides from nitric acid solutions. As extractants, incorporated into the PAN matrix, the N, N’-dimethyl-N, N’- dibutyltetradecylmalonamide (DMDBTDMA), N, N’-dimethyl-N, N’-dioctyl-hexyloxyethylmalonamide (DMDOHEMA), N, N, N’, N’-tetraoctyldiglycolamide (TODGA), 6,6’-bis-(5,6-dipentyl-[1,2,4]triazin-3-yl[2,2’]bipyridinyl (C5BTBP) were used. Weight distribution coefficients Dg of europium and several actinides have been determined for all the composite materials. The kinetics of europium uptake, practical dynamic extraction capacities, and extraction isotherms were also determined. The results obtained revealed that the solid extractants studied are prospective for the partitioning of lanthanides and actinides from liquid radioactive wastes.
