| 中文摘要 | multiwalled carbon nanotubes (mwcnts) were grafted with poly(4-vinylpyridine) (pv4p) in aqueous solution by in situ free radical polymerization of 4-vinylpyridine. the as-prepared pv4p-g-mwcnts hybrids can load phosphotungstic acid (pw) on a large scale by electrostatic interaction, which was characterized by transmission electron microscopy (tem), fourier transform infrared spectroscopy (ftir) and x-ray photoelectron spectroscopy (xps). the as-prepared pws/pv4p-g-mwcnts hybrids were modified onto a carbon glassy electrode. cyclic voltammograms (cvs) show that the electrochemical behavior of the modified electrode follows a four-one-electron surface-confined process of keggin-type pws. the modified electrode can be used as a nitrite sensor. the comparison of cvs shows that the response current of nitrite reduction at the electrode modified with pws/pv4p-g-mwcnts hybrids is 15 times higher than that of pws/mwcnts hybrids in a control experiment at 0.65v (vs. agcl). the amperometric i-t curve for the electrode modified with pws/pv4p-g-mwcnts hybrids exhibits a linear concentration of no(2)(-) ranged from 1.2 to 17.5 mu m with a detection limit of 0.2 mu m.
