Study on NO2 absorption by ascorbic acid and various chemicals

Study on NO2 absorption aimed at seeking a better NO2 absorption chemical at pH 4.5-7.0 for application to existing wet flue gas desulfurization （FGD）. The results from the double-stirred reactor indicated that ascorbic acid has very high absorption rate at this pH range. The rate constant of ascorb...

Summary:Study on NO2 absorption aimed at seeking a better NO2 absorption chemical at pH 4.5-7.0 for application to existing wet flue gas desulfurization （FGD）. The results from the double-stirred reactor indicated that ascorbic acid has very high absorption rate at this pH range. The rate constant of ascorbic acid reaction with NO2 （0～ 1000× 10^-6 mol/mol） is about 3.54× 10^6 mol/（L.s） at pH 5.4～6.5 at 55 ℃.
