Study on NO2 absorption by ascorbic acid and various chemicals
Abstract: 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 3.54×106 mol/(L∙s) at pH 5.4~6.5 at 55 °C.
Key words: NO2, Absorption, Rate constant, Ascorbic acid
