固定化试剂流动注射化学发光法测过氧化氢

Chemiluminescent Flow Injection Analysis with Immobilized Reagent for Determination of Hydrogen Peroxide

本文利用鲁米诺－氯化高铁血红素－过氧化氢发光系统，简化了流动注射流路，建立了快速、灵敏的固定化鲁米诺流动注射化学发光分析法测过氧化氢。检测的浓度范围为１．０×１Ｏ￣（－９）～５．０×１０￣（－４）ｍｏｌ／Ｌ，检出限达２．６×１０￣（－１１）ｍｏｌ／Ｌ。

Luminol-hemin-H_2O_2 system was usedfor chemiluminescent flow injection analysis with im-mobilized luminol to determine hydrogen peroxide.The flow injection system was simplified. The methodis fast and sensitive, and it has a dynamic range of de-tection from 1.0×1O￣(-9)to 5.0×10￣(-4)mol/L with thedetection limit of 2.6×10￣(-11)mol/L for H_2O_2.
