摘　　要：利用鲁米诺作为发光试剂,制备了价廉且可重复使用的鲁米诺-碳糊电化学发光传感器。研究了鲁米诺-碳糊电化学发光传感器在过氧化氢溶液中的电化学发光特性;考察了鲁米诺-碳糊电化学发光传感器在3.0×10-8mol/L过氧化氢中的重现性及传感器寿命。结果表明电化学发光信号与过氧化氢浓度在1.0×10-13～1.0×10-11mol/L范围内呈线性关系。鲁米诺-碳糊电化学发光传感器具有制备方法简单,成本低廉,对H2O2的检测灵敏度高、响应范围宽、分析速度快等优点,有一定的应用价值。A new inexpensive and reusable luminal-carbon paste electrochemical luminescence sensor（LCP-ECLS）was studied.The electrogenerated chemiluminescence（ECL）behavior of this sensor in hydrogen peroxide solution（contain 0.10 moL/L KCl）was investigated when an applied potential was scanned from 0 to 1.0 V.The life and reproducibility of this sensor was studied in 3.0×10^-8 mol/L hydrogen peroxide.The results showed that the ECL signal was linear with the concentration of hydrogen peroxide in the range from 1.0×10^-13 to 1.0×10^-11 mol/L.LCP-ECLS possessed high sensitivity and its preparation was simple,low-cost.
