| 中文摘要 | a sensitive electrochemiluminescent detection scheme by solid-phase extraction at ru(bpy)(3)(2+)-modified ceramic carbon electrodes (cces) was developed. the as-prepared ru(bpy)(3)(2+)-modified cces show much better long-term stability than other nafion-based ru(bpy)(3)(2+)-modified electrodes and enjoy the inherent advantages of cces. the log-log calibration plot for dioxopromethazine is linear from 1.0 x 10(-9) to 1.0 x 10(-4) mol l-1 using the new detection scheme. the detection limit is 6.6 x 10(-10) mol l-1 at a signal-to-noise ratio of 3. the new scheme improves the sensitivity by similar to 3 orders of magnitude, which is the most sensitive ru(bpy)(3)(2+) ecl method. the scheme allows the detection of dioxopromethazine in a urine sample within 3 min. since ru(bpy)(3)(2+) ecl is a powerful technique for determination of numerous amine-containing substances, the new detection scheme holds great promise in measurement of free concentrations, investigation of protein-drug interactions and dna-drug interactions, pharmaceutical analysis, and so on. |
