Study on NO(2) absorption aimed at seeking a better NO(2) absorption chemical at pH 4.5 approximately 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 NO(2) (0 approximately 1,000 x 10(-6) mol/mol) is about 3.54 x 10(6) mol/(Ls) at pH 5.4 approximately 6.5 at 55 degrees C.
旨在寻找一种在pH值约为4.5至7.0的条件下，用于现有湿法烟气脱硫（FGD）的更好的二氧化氮吸收化学品的二氧化氮吸收研究。双搅拌反应器的结果表明，在该pH值范围内，抗坏血酸具有非常高的吸收率。在55℃下，pH值为5.4至6.5时，抗坏血酸与二氧化氮反应的速率常数（0至1000×10⁻⁶mol/mol）约为3.54×10⁶mol/(Ls)。
