摘　　要：基于Fe(o Phen)33+对鲁米诺电化学发光体系的电还原发光信号的增敏作用,建立了一种测定铁离子的电化学发光新方法。在最佳的实验条件下,该方法测定铁(Ⅲ)的线性范围为4.1×10-7～4.1×10-6mol/L,检出限为1.8×10-7mol/L,相对标准偏差小于5%。Based on the enhancing effect of Fe(o-Phen)_3^(3+) on the ECL signal of electro-reducing luminol at the screen-printed electrode, a sensitive and selective ECL method for the determination of Fe(Ⅲ) was described. Under the optimum experimental conditions, the relative ECL enhancing intensity was linearly with Fe(Ⅲ) concentration in the range of 4.1×10^(-7) to 4.1×10^(-6) mol/L with a detection limit of 1.8×10^(-7) mol/L for Fe(Ⅲ).
