| 摘 要： | SWCNTs-PEG-NH2, SWCNTs-2,3-NH2 and SWCNTs-3,4-NH2 nanoparticles could beprepared by covalent modification method of single-walled carbon nanotubes(SWCNTs). The structure ofSWCNTs-PEG-NH2, SWCNTs-2,3-NH2 and SWCNTs-3,4-NH2 nanoparticles could be determined byXPS(X-ray photoelectron spectroscopy). The results showed that the amidation reactions were successful.Ciprofloxacin(CIP) extraction experiments exhibited that, as for SWCNTs-PEG-NH2, the best adsorptioncould be obtained at pH=4 and pH=6, while elution conditions of 0.1mol/L NaOH and 1% SDS couldachieve better elution effect. As for SWCNTs-2,3-NH 2 and SWCNTs-3,4-NH2 , the best adsorption couldbe obtained at pH=6, while the elution condition of 1% SDS could achieve the best elution effect. The addition of Al3+ions could sensitize the fluorescence of ciprofloxacin.
