Affinity of polymer-supported reagents for lanthanides as a function of donor atom polarizability / Yijia Yang in Industrial & engineering chemistry research, Vol. 48 N° 13 (Juillet 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 13 (Juillet 2009) . - pp. 6173–6187 Titre : Affinity of polymer-supported reagents for lanthanides as a function of donor atom polarizability Type de document : texte imprimé Auteurs : Yijia Yang, Auteur ; Spiro D. Alexandratos, Auteur Année de publication : 2009 Article en page(s) : pp. 6173–6187 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Lanthanide-ion  affinities  Donor  atoms  Polymer-supported  reagents Résumé : This review correlates lanthanide-ion affinities with the polarizability of the donor atoms on immobilized ligands to gain an insight into the design of lanthanide-selective polymer-supported reagents. Comparison with the affinities for actinide ions clarifies the correlation. Polymers with different ligands are classified into four categories, based on an increasing order of donor atom polarizability: oxygen, oxygen and nitrogen, nitrogen, and sulfur. Hard−soft acid−base theory is an important determinant of ion−ligand affinities. Additional factors that affect complexation levels include counterion coordination to the metal, protonation of the ligand, and hydration. Selectivity for the lanthanide ions may be engineered into polymer-supported reagents by introducing phosphonic acid ligands.

Ion-exchange resins / Spiro D. Alexandratos in Industrial & engineering chemistry research, Vol. 48 N°1 (Janvier 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°1 (Janvier 2009) . - P. 388-398 Titre : Ion-exchange resins : a retrospective from industrial and engineering chemistry research Type de document : texte imprimé Auteurs : Spiro D. Alexandratos, Editeur scientifique Année de publication : 2009 Article en page(s) : P. 388-398 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Chemistry  Research  Wastewater  treatment  Hydrometallurgy  Chromatography Résumé : Ion-exchange resins comprise one of the most important scientific developments of the 20th century. Their applicability to water softening, environmental remediation, wastewater treatment, hydrometallurgy, chromatography, biomolecular separations, and catalysis was recognized in numerous publications. The principle of covalently bonding ligands to cross-linked polymer networks became the basis for the area of polymer-supported reagents. The journal Industrial & Engineering Chemistry Research and its predecessors have published some of the most important papers in this field. In celebration of its 100th anniversary, this review provides a retrospective of ion-exchange resins through publications appearing in this journal.
