Synthesis, characterization and properties of tropine-based ionic liquids gels

Author affiliations

Abstract

A new type of tropine-based ionic liquid (IL) gels were synthesized and characterized by Fourier transform infrared spectra (FT-IR), elemental analysis (EA), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and zeta potential measurements, and the swelling behavior of ionic liquid (IL) gels were further investigated. FT-IR, EA and XRD indicated the successful synthesis of IL gels, TGA analysis showed that the IL gels had good thermal stability, SEM showed that the introduction of ILs made the gel surface rough, and increased the specific surface area. The swelling values of IL gels were well correlated by the second-order kinetics equation with the correlation coefficients of at least 0.99. Furthermore, the IL gels were used as adsorbent to adsorb bovine albumin (BSA), the maximum adsorption capacity was up to 700 mg gāˆ’1.
