| Abstract: | Nitrogen, phosphorus co-doped porous carbon nanofiber (N, P-PCNF) is prepared by electrospinning the mixed solution of polyacrylonitrile (PAN), polyvinylpyrrolidone (PVP) and phosphoric acid followed by carbonization. The N, P-PCNF as a modified electrode material is directly used to fabricate an electro-chemiluminescent sensor for determination of cyproheptadine, and owing to the large specific area, more active sites and promotion of electron transfer, the sensor exhibits high electro-catalytic activity, high sensitivity, a good linear relationship ranging from 1.0 × 10−7 to 1.0 × 10−5 mol L−1 and a low detection limit (2.89 × 10−8 mol L−1). In addition, the good recoveries indicate that the sensor is a promising device for the detection of cyproheptadine in real samples.Nitrogen, phosphorus co-doped porous carbon nanofiber is as electrode modified material to fabricate an electro-chemiluminescent sensor for detecting cyproheptadine. |
