| 中文摘要 | a new electrochemiluminescence (ecl) microoptoprobe with simple structure. small sampling volume and high efficiency was developed. it was constructed by fixing the transparent gold mini-grid on the end surface of the optical fiber, and by surrounding the fiber with the counter- and reference electrodes to form a self-contained three-electrode system. the use of mini-grid electrode increased the surface area and collection efficiency. which resulted in higher ecl signal and better sensitivity. the counter electrode together with one end of the fiber formed a mini-vessel, which eliminated the need of additional container and allowed to perform ecl detection in a very small volume (about 10 mul). the microoptoprobe obtained was characterized with the ru(bpy)(3)(2-)-tripropylamine system and was applied for the determination of oxalate and chlorpromazine (cpz). detection limits (s/n = 3) were 5 x 10(-7) and 1 x 10(-6) mol l(-1) for oxalate and cpz. respectively. the linear range for oxalate and cpz extended from 1 x 10(-6) to 1 x 10(-3) mol l(-1), and from 5 x 10(-6) to 5 x 10(-4) mol l(-1). respectively. |
