Effect of the Functional Molecule on Adsorption Characteristics of Lithium-selective Surface Imprinted Polymer.

Synergistic Solvent Impregnated Resin for Adsorptive Separation of Lithium Ion

“…On the basis of these observations the stoichiometry of the metal complex in the SIR is suggested to be Li + :C 11 phβDK:TOPO = 1:1:1. The present impregnated resin possesses much higher adsorption capacity for Li + than the molecular imprinted polymeric adsorbent containing C 11 phβDK and TOPO, though there were no data of the maximum adsorption amount of the molecular imprinted polymeric adsorbent based on the adsorption isotherm. , …”

“…Combination of solvent extraction with adsorption and/or ion exchange, such as with a solvent-impregnated resin (abbreviated as SIR) − and microcapsules encapsulating extractant, − has been investigated as a second generation extraction system. Recently, as a Li + separation system a molecular imprinted polymeric adsorbent containing a mixture of C 11 phβDK and TOPO has been developed to combine a synergistic extraction system with the ion exchange method. , Although the adsorbent possesses high selectivity for Li + , the loading capacity is quite poor (of the order of several micromoles per gram). The SIR is easily prepared by simply treating the polymeric resin with an organic solution of extractant, and the loading capacity of the SIR for the metal ion is sufficiently high (of the order sub-millimoles per gram).…”
