| 中文摘要 | preparation and characterisation of core-shell cnts@mips nanocomposites and selective removal of estrone from water samples |
| 英文摘要 | this paper reports the preparation of carbon nanotubes (cnts) functionalized with molecularly imprinted polymers (mips) for advanced removal of estrone. cnts@est-mips nanocomposites with a well-defined core-shell structure were obtained using a semi-covalent imprinting strategy, which employed a thermally reversible covalent bond at the surface of silica-coated cnts for a large-scale production. the morphology and structure of the products were characterised by transmission electron microscopy and fourier transform infrared spectroscopy. the adsorption properties were demonstrated by equilibrium rebinding experiments and scatchard analysis. the results demonstrate that the imprinted nanocomposites possess favourable selectivity, high capacity and fast kinetics for template molecule uptake, yielding an adsorption capacity of 113.5 mu mol/g. the synthetic process is quite simple, and the different batches of synthesized cnts@est-mips nanocomposites showed good reproducibility in template binding. the feasibility of removing estrogenic compounds from environmental water using the cnts@est-mips nanocomposites was demonstrated using water samples spiked with estrone.
