Ethyl formate is extensively used as food flavor, fungicide, and larvicide. It naturally exists in coffee, fruits, honey, brandy, and rum as well as dust clouds in an interstellar space of the Milky Way galaxy. Herein, its electrochemiluminescence (ECL) property has been firstly investigated. It shows intense ECL in reaction with Ru(bpy)₃²⁺ as luminophore, and thus a rapid and sensitive detection method for ethyl formate is proposed. Effects of pH, working potential, scan rate, and concentration of Ru(bpy)₃²⁺ were studied. ECL spectrum analysis was used to reveal the reaction mechanism. At the optimized experimental conditions, a linear relationship between ECL intensities and concentrations of ethyl formate is observed from 3.0 μM to 1.0 mM (R² = 0.997). The limit of detection for ethyl formate is 0.7 μM (S/N = 3). The relative standard deviation with 1.0 mM concentration of ethyl formate for nine analyses is 2.7%. A 101.20–102.10% recovery was obtained in a real samples analysis.

甲酸乙酯被广泛用作食品香料，杀真菌剂和杀幼虫剂。它自然存在于银河系星际空间中的咖啡，水果，蜂蜜，白兰地和朗姆酒以及尘埃云中。在此，首先研究了其电化学发光（ECL）性质。它与Ru（bpy）₃ ²⁺作为发光体反应时显示出强烈的ECL ，因此提出了一种快速灵敏的甲酸乙酯检测方法。研究了pH，工作电势，扫描速率和Ru（bpy）₃ ²⁺浓度的影响。用ECL光谱分析揭示了反应机理。在优化的实验条件下，从3.0μM到1.0 mM（R²  = 0.997）。甲酸乙酯的检出限为0.7μM（S / N  = 3）。进行9次分析时，甲酸乙酯浓度为1.0 mM的相对标准偏差为2.7％。在真实样品分析中，回收率达到101.20–102.10％。
