Hydrophobic Ionic Liquid Modified Thermo-responsive Molecularly Imprinted Monolith for Selective Recognition and Separation of Tanshinones |
| 초록 |
A hydrophobic ionic liquid modified thermo-responsive molecularly imprinted monolith was synthesized using N-isopropylacrylamide as thermo-responsive monomer and long chain hydrophobic ionic liquid as auxiliary modification monomer. When the column temperature was changed, the synthesized monolithic column was successfully applied to the selective separation of homologue tanshinones within short time and eluted only by water (mobile phase). The negative Gibbs free energy values showed that the transfer of the tanshinones from the mobile phase to the stationary phase on this monolithic column was a thermodynamically spontaneous process. In this proposed thermo-responsive chromatography method, the separation of homologue analytes can be achieved by changing the column temperature and the use of water as the mobile phase would decrease the economic cost and organic pollution. |
