应用自制的ＥＣＬ－１型电致化学发光仪，对新试剂６－（２－羟基－４－二乙基氨苯偶氮）－２．３－二氢－１，４－酞嗪二酮（ＨＤＥＡ）在Ｎａ２ＣＯ３－ＮａＨＣＯ３缓冲介质中的电化学发光行为作了研究．结果发现，当介质ｐＨ值为 １０．５４时，在一定的实验条件下，施加 １．７Ｖ （ＶＳ．ＳＣＥ）三角波脉冲电压，体系的发光强度与ＨＤＥＡ浓度在５．０ × １０－９～１．０×１０－６ｍｏｌ／Ｌ范围内呈线性关系，反应的检测限达１．０×１０－９ｍｏｌ／Ｌ．
The new reagent 6- (2-hydroxy-4-diethylaminophenylazo) -2,3-dihydro-1,4-phthalazinedione ( HDEA) in Na2CO3-NaHCO3 buffer medium electrochemical luminescence behavior was studied. The results showed that the pulsed voltage of 1.7V (VS.SCE) was applied under certain experimental conditions when the pH value of the medium was 10.54. The luminescence intensity of the system and the concentration of HDEA were in the range of 5.0 × 10-9 ~ 1 .0 × 10-6mol / L showed a linear relationship between the detection limit of the reaction of 1.0 × 10-9mol / L.
