| 中文摘要 | the combination of in situ surface plasmon resonance (spr) with electrochemistry was used to investigate the electrochemical doping/dedoping processes of anions on a polyaniline (pan)-modified electrode. electrochemical spr characteristics of the pan film before and after doping/dedoping were revealed. the redox transformation between the insulating leucoemeraldine, and the conductive emeraldine, corresponding to the doping/dedoping of anion, can lead to very distinct changes in both the resonance minimum angle and the shape of spr curve. this is ascribed to the swelling/shrinking effect, and the change of the pan film in the imaginary part of the dielectric constant resulted from the transition of the film conductivity. in situ recording the time evolution of reflectance change at a fixed angle permits the continuous monitoring of the kinetic processes of doping/dedoping anions. the size and the charge of anions, the film thickness, as well as the concentration of anions are shown to strongly influence the rate of ingress/egress of anions. the time differential of spr kinetic curves can be well applied in the detecting electroinactive anion by flow injection analysis. the approach has higher sensitivity and reproducibility compared with other kinetic measurements, such as those obtained by amperometry. |
