Ion exchange equilibria of heavy metals in aqueous solution on new chelating resins of sporopollenin

Immobilization of Candida rugosa lipase on sporopollenin from Lycopodium clavatum

“…This material may be usefully applied at high temperatures, since it is stable under high temperature and in the presence of concentrated acids [25,31,32]. Infrared and 13 C NMR spectroscopic studies on sporopollenin derived from pteridophyta and spermatophyta have shown that sporopollenin has aliphatic, aromatic, hydroxyl, carbonyl/carboxyl and ether functions in various portions in its polymeric structure [33].…”

Equilibrium and kinetics of heavy metal ion exchange

“…Furthermore, it can be as well categorized on the basis of functional groups such as cationic exchange resins, anion exchange resins, and chelating exchange resins (Dorfner, 1991). Depending on the functional groups, ion-exchange resin www.elsevier.com/locate/jcice Journal of the Chinese Institute of Chemical Engineers 38 (2007) [71][72][73][74][75][76][77][78][79][80][81][82][83][84] can deal properly with several heavy metals such as copper, nickel, cobalt, cadmium, zinc, and aluminum (Ersoz et al, 1995;Fernández et al, 2005;Kiefer and Höll, 2001;Kilislioglu and Bilgin, 2003).…”

Determination of the rate control step of purin and pyrimidine bases adsorption on cobalt(II)–CDAE-sporopollenin

“…The important experimental work on this matter has been carried out [11][12][13][14][15][16][17][18][19], but the adsorption kinetic of ligands on CDAE-sporopollenin has not been considered sufficiently in detail. This study was conducted to designate rate control step of nucleic acid bases and nucleosides adsorption on chelating cobalt(II)-CDAE-sporopollenin resin.…”
