| 英文摘要 | the applications of carbon nanotube (cnt) as solid-phase extraction matrix and bulk modification material in electrochemiluminescence (ecl) have been demonstrated for the first time. the bulk modification of ru(phen) (2+)(3) has been achieved through the preparation of ru(phen) (2+)(3)/nafion modified cnt ceramic electrode. the bulk modification method has the advantages of easy electrode surface renewal and facile electrode preparation over surface immobilization approaches. moreover, ru(phen)(3)(2+)/nafion modified cnt ceramic electrode can serve as an excellent solid- phase microextraction matrix because of the presence of cnt in the electrode. the combination of the ru(phen)(3)(2+)/nafion modified cnt ceramic electrode with solid-phase extraction enables ultrasensitive detection of perphenazine. the log-log calibration plot for perphenazine is linear from 1 x 10(-6) to 1 x 10(-11) m with a detection limit of 5.8 x 10(-12) m. the ru(phen)(3)(2+)/nafion modified cnt ceramic electrode shows better detection limit than ru(phen)(3)(2+)/nafion modified graphite ceramic electrode by about two orders of magnitude because of strong adsorption capacity and large adsorbing area of multi-walled cnt as well as low ecl background. it is one of the most sensitive methods for the ru(phen)(3)(2+) ecl determination of coreactants so far. the detection takes less than 3 min, which makes this method promising for on-site detection. this method was also successfully applied for the determination of perphenazine in human urine samples spiked with perphenazine. the ru(phen)(3)(2+)/nafion modified cnt ceramic electrode exhibits outstanding long-term stability and reproducibility. the remarkable extraction capability and outstanding long-term stability of ru(phen)(3)(2+)/nafion modified cnt ceramic electrode as well as the advantages of bulk modification method make the present detection strategy promising for ultrasensitive detection of organic compounds.
