设计合成了一个识别H₂O₂的荧光探针。基于探针与过氧化氢荧光增强现象，建立了检测过氧化氢的荧光分析方法。检测过氧化氢的线性范围为0~180 mmol/L，检出限为3.482 μmol/L。将探针用于测定实际样品中的过氧化氢，回收率令人满意。本探针具有灵敏度高、选择性好的优点。

A fluorescent probe for identifying H₂O₂ is designed and synthesized.Based on the increasing fluorescence between probe and H₂O₂,a fluorescent determination method is established to determine H₂O₂.The fluorescence enhances linearly with the concentration of H₂O₂ in the range of 0-180 mmol·L^-1 with a detection limit of 3.482 μmol·L^-1.Satisfied recoveries can be obtained when the fluorescent probe is used to detect H₂O₂ in real samples.This probe is proved to have the advantages of high selectivity and sensitivity.
