A novel solid phase extraction method for separation of actinides and lanthanides from high acidic streams

Solid-phase extraction technology for actinide and lanthanide separations in nuclear fuel reprocessing

“…It is also interesting to note © Woodhead Publishing Limited, 2011 that all metals could be completely removed from the column with deionized water. Raju and Subramanian (2005, 2007a, 2007b and Maheswari and Subramanian (2005) have used similar grafting techniques to attach other ligands, such as CMPO, dimethyl amino-phosphono-methyl phosphinic acid (DAPPA), N,N,-di-hexyl succinamic acid (DHSA) and 4-ethoxy-N,N-dihexylbutanamide (EDHBA) to Merrifi eld chloromethylated (MCM) or AXAD-16 polymer resins. The authors report the physicochemical properties of these grafted ligand-polymer resins and performed bench-scale tests to evaluate their utility for effecting various U, Th and Ln(III) element separations.…”

PVC Coated with an Indole Derivative-Loaded Triton X-100: a New Sorbent for Cu, Zn and Mn Ions

“…One of the most important factors for quantitative recoveries in a solid phase extraction procedure is the pH of the aqueous phase [44][45][46][47][48][49][50][51]. The effect of pH on the preconcentration of metal ions on the Triton X-100 loaded with INMI was studied by a determination using 250 mL of 0.02 µg mL −1 ions in a pH range of 2.0-9.0.…”

A solid phase extraction procedure for Fe3+, Cu2+ and Zn2+ ions on 2-phenyl-1H-benzo[d] imidazole loaded on Triton X-100-coated polyvinyl chloride

“…This reveals that the mechanism of sorption of ions is pH dependent and pH could affect the stability of the complexes. One of the most important factors in a solid phase extraction procedure is the pH of the aqueous phase for the quantitative recoveries [26][27][28][29][30][31][32][33]. The reaction between analyte ions and the complexing agent can be influenced by changes of pH value.…”
