/ method of analysis for hydroperoxyl radical/superoxide anion radical

摘要

present invention is oxidation of wastewater treatment processes in the important role of oxidizing agents in hydro peroxy radicals / superoxide anion radical (HO ₂ and / O ₂ ^- and) relates to an improved method of measuring, I want to analyze generating a peroxy radical / superoxide anion radical by irradiation with ultraviolet rays to a solution; Transfer the solution to the reactor step to inject the pH-adjusted solution to a reactor; Iron in solution (a 3) of ethylenediaminetetraacetic acid (Fe ^{3 +} -EDTA) and terephthalic acid that by putting the reaction step; Measuring the fluorescence intensity of the solution; And peroxy radical / superoxide provides dihydro peroxy radicals, including the step of calibration, the concentration of the anion radical / analysis of superoxide anion radical. According to the invention, without a reference material, and to measure the concentration of the peroxy radical / superoxide anion radical, as compared to using the acid as a conventional navigation materials, peroxy radical / superoxide anion radical and the reaction is detected substance the fluorescence intensity of the higher sensitivity is better and become more accurate measurement.
