| 中文摘要 | a new method for immobilization of a chemiluminescent reagent is presented. it is based on immobilizing hematin, a catalyst for luminol reaction, in the bulk of a carbon paste electrode. bulk-immobilization allows renewal of the surface by simple polishing or cutting to expose anew and fully active surface in the case of fouling or deactivation by other means. by using a hematin-modified carbon paste electrode, the applied potential shifted negatively compared with that of unmodified carbon paste electrode or a glassy carbon electrode. the shift in potential changed the reaction processes and effectively stabilized the chemiluminescent signal during successive measurements. under this condition, the signal was stable during 3 hours of continuous operation. the log-log plots of the emitted light intensity vs. luminol concentration and hydrogen peroxide concentration were linear over the region 10(-8)-10(-3) mol l-1 with a correlation coefficient of 0.999 and 3.9 x 10(-6)-10(-3) mol l-1 with a correlation coefficient of 0.994, respectively. application of this method for other chemiluminescent and bioluminescent systems is suggested. |
