摘要

Abstract

A composite-liquid absorbent (CLA)

NaClO/KMnO

for simultaneous desulfurization and denitrification (SDD) was studied in a homemade bubbling reactor. The experimental results showed that the CLA configured by sodium hypochlorite (NaClO) and potassium permanganate (KMnO

) had a very good synergistic effect on SDD. The effects of NaClO concentration (

)

KMnO

concentration (

)

gas space velocity (

)

initial pH value

and temperature of the absorption liquid (

) on efficiencies of the SDD were investigated. Under the optimal reaction conditions

the best removal efficiencies were 100% for sulfur dioxide (SO

) and above 94% for nitric oxide (NO). The ion chromatography and titration were used to analyze the changes of both the ion species and concentrations in the liquid before and after the reaction. According to the experiment results and related literature

the reaction mechanism of the SDD based on the CLA was proposed.
