To solve the difficulty of easy oxidation of Fe^IIEDTA in nitric oxide removal, Fe^IIEDTA combined with sodium erythorbate (SE) was employed for nitric oxide absorption. SE quickly reduced Fe^IIIEDTA to Fe^IIEDTA and maintained Fe^IIEDTA activity for a long time in the air. The influences of various operating parameters such as Fe^IIEDTA concentration, SE concentration, original pH value and temperature on NO removal in the bubbling device were examined preliminarily. The results reveal that the SE significantly enhanced nitric oxide absorption with Fe^IIEDTA. Nitric oxide absorption efficiency increased with the increase in the concentration of absorbent components or the decrease in temperature. Weak alkalinity (about pH 8.0) is beneficial to NO absorption. Besides, the NO removal efficiency continually decreased as the NO or O₂ concentration increased, while the NO removal efficiency increased first and then decreased as the SO₂ concentration increased. However, pH and temperature hardly affected nitric oxide absorption efficiency at Fe^IIEDTA with high concentration. Finally, the kinetic studies demonstrated that NO absorption by mixed Fe^IIEDTA and SE was more effective in reducing total mass transfer resistance and enlarging the NO flux compared with the normal Fe^IIEDTA approach. The absorption process was controlled by the liquid film.

为解决Fe ^II EDTA易氧化去除一氧化氮的难点，采用Fe ^II EDTA与异抗坏血酸钠（SE）结合进行一氧化氮吸附。SE迅速将Fe ^III EDTA还原为Fe ^II EDTA，并在空气中长时间保持Fe ^{II EDTA活性。初步考察了Fe II} EDTA浓度、SE浓度、初始pH值和温度等各种操作参数对鼓泡装置中NO脱除的影响。^{结果表明，SE 显着增强了 Fe II}对一氧化氮的吸收乙二胺四乙酸。一氧化氮的吸收效率随着吸收剂组分浓度的增加或温度的降低而增加。弱碱性（约 pH 8.0）有利于 NO 的吸收。此外，随着NO或O ₂浓度的增加，NO的去除效率不断下降，而NO的去除效率随着SO ₂浓度的增加呈先上升后下降的趋势。然而，pH 和温度对高浓度Fe ^II EDTA 的一氧化氮吸收效率几乎没有影响。最后，动力学研究表明，与普通 Fe ^{II相比，混合 Fe II} EDTA 和 SE 吸收 NO 在降低总传质阻力和扩大 NO 通量方面更有效EDTA 方法。吸收过程由液膜控制。
