Adsorption of Lanthanide(III) Cations on Cross-Linked Ionic Polymer, Composition and Thermal Analysis of the Formed Composites
Abstract The adsorption of lanthanide(III) cations by a strongly basic cross-linked polymer containing $ R_{4} %$ N^{+} $ groups was studied at 21 and 50°C. At both temperatures the sorption is best described with the Langmuir model. The maximum adsorption at both 21 and at 50°C increases in the ser...

| 520 | |a Abstract The adsorption of lanthanide(III) cations by a strongly basic cross-linked polymer containing $ R_{4} %$ N^{+} $ groups was studied at 21 and 50°C. At both temperatures the sorption is best described with the Langmuir model. The maximum adsorption at both 21 and at 50°C increases in the series: $ La^{3+} $ < $ Eu^{3+} $ < $ Nd^{3+} $ < $ Er^{3+} $. The results show that polymers containing strongly basic groups can, under certain conditions, be used to separate lanthanide(III) cations in solutions containing mono- and bivalent cations. SEM EDX studies show that $ La^{3+} $, $ Nd^{3+} $, $ Eu^{3+} $ and $ Er^{3+} $ form composites in the polymer phase. The elemental composition of structural units of the composites is $ La_{1} %$ Cl_{13.7} %$ S_{64.3} %$ O_{287.7} %$ N_{122.6} %$ C_{2869} $, $ Nd_{1} %$ Cl_{27.4} %$ S_{50.7} %$ O_{391.6} %$ N_{169.3} %$ C_{2896} $, $ Eu_{1} %$ Cl_{8.5} %$ S_{50.8} %$ O_{285} %$ N_{130} %$ C_{2118} $ and $ Er_{1} %$ Cl_{36.8} %$ S_{263.9} %$ O_{1106} %$ N_{447} %$ C_{8657} $. The thermodynamic parameters of the sorption process are calculated: free energy, enthalpy, and entropy. Thermogravimetric analysis made it possible to determine the stability of the formed composites, the stages of their decomposition and the corresponding kinetic parameters. | ||

Abstract The adsorption of lanthanide(III) cations by a strongly basic cross-linked polymer containing $ R_{4} %$ N^{+} $ groups was studied at 21 and 50°C. At both temperatures the sorption is best described with the Langmuir model. The maximum adsorption at both 21 and at 50°C increases in the series: $ La^{3+} $ < $ Eu^{3+} $ < $ Nd^{3+} $ < $ Er^{3+} $. The results show that polymers containing strongly basic groups can, under certain conditions, be used to separate lanthanide(III) cations in solutions containing mono- and bivalent cations. SEM EDX studies show that $ La^{3+} $, $ Nd^{3+} $, $ Eu^{3+} $ and $ Er^{3+} $ form composites in the polymer phase.

At both temperatures the sorption is best described with the Langmuir model. The maximum adsorption at both 21 and at 50°C increases in the series: $ La^{3+} $ < $ Eu^{3+} $ < $ Nd^{3+} $ < $ Er^{3+} $. The results show that polymers containing strongly basic groups can, under certain conditions, be used to separate lanthanide(III) cations in solutions containing mono- and bivalent cations. SEM EDX studies show that $ La^{3+} $, $ Nd^{3+} $, $ Eu^{3+} $ and $ Er^{3+} $ form composites in the polymer phase. The elemental composition of structural units of the composites is $ La_{1} %$ Cl_{13.7} %$ S_{64.3} %$ O_{287.7} %$ N_{122.6} %$ C_{2869} $, $ Nd_{1} %$ Cl_{27.4} %$ S_{50.7} %$ O_{391.6} %$ N_{169.3} %$ C_{2896} $, $ Eu_{1} %$ Cl_{8.5} %$ S_{50.8} %$ O_{285} %$ N_{130} %$ C_{2118} $ and $ Er_{1} %$ Cl_{36.8} %$ S_{263.9} %$ O_{1106} %$ N_{447} %$ C_{8657} $. The thermodynamic parameters of the sorption process are calculated: free energy, enthalpy, and entropy. Thermogravimetric analysis made it possible to determine the stability of the formed composites, the stages of their decomposition and the corresponding kinetic parameters.</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lisa, Gabriela</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2="

Adsorption of Lanthanide(III) Cations on Cross-Linked Ionic Polymer, Composition and Thermal Analysis of the Formed Composites |
| abstract |
Abstract The adsorption of lanthanide(III) cations by a strongly basic cross-linked polymer containing $ R_{4} %$ N^{+} $ groups was studied at 21 and 50°C. At both temperatures the sorption is best described with the Langmuir model. The maximum adsorption at both 21 and at 50°C increases in the series: $ La^{3+} $ < $ Eu^{3+} $ < $ Nd^{3+} $ < $ Er^{3+} $. The results show that polymers containing strongly basic groups can, under certain conditions, be used to separate lanthanide(III) cations in solutions containing mono- and bivalent cations. SEM EDX studies show that $ La^{3+} $, $ Nd^{3+} $, $ Eu^{3+} $ and $ Er^{3+} $ form composites in the polymer phase. The elemental composition of structural units of the composites is $ La_{1} %$ Cl_{13.7} %$ S_{64.3} %$ O_{287.7} %$ N_{122.6} %$ C_{2869} $, $ Nd_{1} %$ Cl_{27.4} %$ S_{50.7} %$ O_{391.6} %$ N_{169.3} %$ C_{2896} $, $ Eu_{1} %$ Cl_{8.5} %$ S_{50.8} %$ O_{285} %$ N_{130} %$ C_{2118} $ and $ Er_{1} %$ Cl_{36.8} %$ S_{263.9} %$ O_{1106} %$ N_{447} %$ C_{8657} $. The thermodynamic parameters of the sorption process are calculated: free energy, enthalpy, and entropy. Thermogravimetric analysis made it possible to determine the stability of the formed composites, the stages of their decomposition and the corresponding kinetic parameters. © Pleiades Publishing, Ltd. 2021.
