本工作的目的是开发一种新的湿式洗涤过程中使用Fe（VI）的同时去除气态NO和SO（2）。研究了在pH为9.0-11.0的碱性水溶液中Fe（VI）氧化SO（2）和NO的反应。NO和SO（2）与Fe（VI）氧化的化学计量摩尔比被确定为接近3.0。在pH 9.0-11.0的反应中，通过离子色谱法鉴定硫酸盐和硝酸盐为最终产物。从工业应用的角度探讨了高铁酸盐连续进料同时去除多种气体污染物的可行性。结果表明，随着Fe（VI）浓度的增加，NO和SO2的去除率提高，在常温常压下，Fe（VI）湿式洗涤法对NO和SO2的去除率分别达到90%和100%以上。结果表明，Fe（VI）是一种有效的同时脱除NO和SO2的湿式洗涤剂。
The objective of this work was to develop a novel wet-scrubbing process using Fe(VI) for the simultaneous removal of gaseous NO and SO(2). The oxidation of SO(2) and NO with Fe(VI) was studied in aqueous solution at alkaline pH (9.0-11.0). A stoichiometric molar ratio for NO and SO(2) oxidation with Fe(VI) was determined to be nearly 3.0. Sulfate and nitrate was identified as final products by ion chromatography from the reaction at pH 9.0-11.0. The feasibility of simultaneous removal of multiple gas pollutants with the continuous feeding of ferrate in lab-scale was investigated from the view of industrial application. It was found that the removal efficiency of NO and SO(2) was enhanced with the increase of Fe(VI) concentration, more than 90% NO removal efficiency and 100% SO(2) removal efficiency were achieved by wet-scrubbing process using Fe(VI) at room temperature and ambient atmosphere. The results demonstrate that Fe(VI) could be an effective wet-scrubbing agent for the simultaneous removal of NO and SO(2).
