Facilitated transport of americium(III) from nitric acid media using dimethyldibutyltetradecyl-1,3-malonamide

Selective separation of radio-cesium from acidic solutions using supported liquid membrane containing chlorinated cobalt dicarbollide (CCD) in phenyltrifluoromethyl sulphone (PTMS)

“…The effective membrane area (Q), computed by multiplying the geometrical area and membrane porosity, was equal to 3.14 cm 2 . Thickness and porosity of the membrane were ascertained as reported earlier [17].…”

Simultaneous separation and purification of plutonium and americium from aqueous nitrate solutions using extractant impregnated macroporous polymeric beads

“…Solvent extraction [5,6], extraction chromatography [7,8], solid phase extraction using functionalized resins [9,10], biosorption [11], membrane techniques [12][13][14][15] and a number of adsorbents [16][17][18] have been extensively used for separation and purification of plutonium and americium. However, some drawbacks of the afore-mentioned techniques (as outlined below) have always attracted the researchers to develop improved and technically viable methodologies for clean separations.…”

Facilitated transport of tetravalent plutonium from nitric acid medium using a novel extractant – BenzoDODA

“…During operation of the process, depending on the 15 performance of various process parameters some amount of Pu 16 ($5-10 ppm) remains unrecovered and goes to high level waste 17 (HLW) along with other fission products, structural materials and 18 unrecovered U. Also in the operation of the PUREX plant various 19 streams of wastes are generated which contain significant quantity 20 of Pu in presence of other contaminants. Pu has great strategic 21 importance and also is used for electricity production in fast 22 reactors.…”
