Preparation and adsorption property of solanesol molecular imprinted polymers

Abstract

Molecular imprinted polymers of solanesol (SSO-MIPs) were synthesized through solution polymerization using solanesol (SSO) as the template molecule, N-vinylpyrrolidone (NVP) and acrylic acid (AA) as functional monomers, ethyleneglycol dimethacrylate (EGDMA) as cross-linker and azodiisobutyronitrile (AIBN) as initiator. Focused on the adsorption capacity and separation degree of MIP-SSO to SSO from the mixture of SSO and Triacontanol (TAL), the effects of the monomers, cross-linker and initiators on them were investigated and optimized. Finally, the structure of MIP-SSO prepared under the optimal conditions was characterized using Fourier transform infrared and scanning electron microscope. To obtain the more objective results, non-imprinted molecular polymers (NMIPs) prepared under the same condition was also characterized as contrast.

Preparation and characterization of a novel molecularly imprinted polymer for the separation of glycyrrhizic acid

“…Because the above pores, cavities and free efficient sites related to the adsorption capacities and adsorption kinetics directly, the higher adsorption capacities and speeder adsorption rated could be understood naturally. To evaluate the chloromethylation kinetics, the pseudo‐first and pseudo‐second order models were employed to simulate the experimental kinetics data .…”

“…The maximum absorbance wavelength of the chloroform solution of GA and GL were investigated with 752N UV spectrophotometer (Shanghai Precision and Scientific Instrument, China) by full wavelength scanning method using chloroform as a blank . The wavelength range here adopted was 200–400 nm, the scan interval was 2 nm, and the results are shown in Fig .…”

“…China) by full wavelength scanning method using chloroform as a blank [9,10]. The wavelength range here adopted was 200-400 nm, the scan interval was 2 nm, and the results are shown in Fig 2. The maximum absorbance peaks of GA and GL were 254 and 278 nm, respectively, and separated completely, which meant the concentration determination of GA and GL in the later experiment could be carried out directly.…”

“…Since MIPs are very selective toward the target compound, they are commonly used as recognition elements in the fabrication of biosensors. MIPs have the ability to bind target compounds not only by their 3-D shape, because the incorporation of specific binding groups into the selective cavities of a polymeric network enhances its affinity and selectivity toward the target analyte [3,4,5,6,7,8,9,10]. …”
