Subsequently, hydrogen peroxide (H2O2) was measured using a (p-hydroxyphenyl) acetic acid (POHPAA) analysis method . Typically, a certain volume of fluorescence reagent (potassium hydrogen phthalate: 8.2 g/L, p-hydroxyphenylacetic acid: 270 mg/L, and type II horseradish peroxidase: 30 mg/L) was preadded into the reaction system. 1.0 mL of sample wgas then withdrawn at an interval time of 2 h and then mixed with 1.0 mL of 1.0 mol/L NaOH for 10 min for measuring the intensity of the fluorescence emission at 409 nm excited at 315 nm. 首先你自己要先做一个标准曲线 |
