Magnetic mol. imprinted polymers (MIPs) based on 4-vinylbenzyltrimethylammonium chloride (VBTAC) and 4-vinylbenzoic acid (VBA) deep eutectic solvent as dual functional monomers was successfully synthesized for the specific recognition of laminarin. The MIPs were characterized by transmission electron microscopy, SEM, Fourier transform IR spectroscopy, thermal gravimetric anal., and vibrating sample magnetometer anal. The results showed that the MIPs were spheres of a uniform size, with the surface rich in cavities and excellent superparamagnetism properties. The adsorption experiments showed that MIPs conform to pseudo-second-order kinetics and Langmuir isotherm adsorption. The maximum adsorption capacity under optimal conditions was 322.58 μg·mg-1 and the imprinting factor was 2.13. Under the optimized conditions, the limit of detection (LOD) of the developed material was 6.6 μM. Linearity of the material was obtained within the range 20-800 μM with a coefficient of determination (r2) being better 0.999. Relative standard deviations (RSDs) were less than 3.96%, and satisfactory recoveries were between 94.55 and 97.39%. The actual sample anal. manifested that MIPs could effectively sep. laminarin from Laminarin japonica Aiesch. Graphical abstract: [graphic not available: see fulltext] In the experiment, the researchers used many compounds, for example, Laminarin (cas: 9008-22-4Formula: 0).
Laminarin (cas: 9008-22-4) belongs to tetrahydropyran derivatives. Tetrahydropyran is a useful synthetic intermediate. Tetrahydropyranyl (THP-) ethers derived from the reaction of alcohols and dihydropyran are common intermediates in organic synthesis. Pyran derivatives such as pyran flavonoids are biologically important. Monosaccharides containing six-membered rings are called pyranose.Formula: 0
