摘　　要：研究了钙黄绿素-S2O82-体系的电化学发光性能,考察了pH、K2S2O8浓度及钙黄绿素浓度对其电化学发光强度的影响,推测了其电化学发光机理,并基于对乙酰氨基苯酚对该体系电化学发光强度的猝灭作用,建立了一种电化学发光测定对乙酰氨基苯酚的新方法.其线性范围为1.0×10-6-1.0×10-4 mol/L,检出限为3.3×10-7 mol/L.The cathodic ECL property of calcein-S2O82-system was studied.The effect of pH,K2S2O8 concentration and calcein concentration on the ECL intensity was investigated and the possible mechanism for the ECL behavior of calcein-S2O82-system was proposed.In addition,a new method of the determination of the acetaminophen was established,based on the quenching effect of acetaminophen on the ECL intensity of calceinS2O82-system.
