摘要: 本文在自制的ECL-1型电致化学发光仪上,用电致化学发光分析法研究了稀土元素钇(Ⅲ)催化新试剂5-(对-苯胺偶氮)-2,3-二氢-1,4-酞嗪二酮(简称ADPD)的电致化学发光行为。

Abstract: A sensitive method for determination of trace element yttrium (Ⅲ) in a buffer medium of Na2CO3-NaHCO3-(NH4)2C2O4(pH 10.27) is reported based on the electrochemiluminescence of the new reagent 5-(p-aminophenylazo)-2, 3-dihydro-1, 4-phthalazine-l, 4-dione(ADPD). The detection limit of yttrium is 0. 002 ppm,and linear calibration range extends from 0. 01 to 0. 6 ppm. The influence factors and mechanism of the ECL of Y(Ⅲ) catalyzing ADPD emission process are discussed.

Key words: Electrochemiluminescence, ADPD, Yttrium
