Abstract
A gas purification agent includes an electronegative film-forming agent and a foaming agent. The electronegative film-forming agent accounts for 20-80 wt % of the gas purification agent, while the foaming agent accounts for 20-80 wt % of the gas purification agent. The gas purification agent of such a composition can be used as a haze removing agent to effectively remove fine dust particles such as PM10 and PM2.5 from the air. The gas purification agent includes 2.5-25 wt % of the electronegative film-forming agent, 2.5-25 wt % of the foaming agent, and 50-95 wt % of a desulfurizing agent. The gas purification agent of such a composition can be used as a desulfurizing agent to remove sulfur-containing compounds from industrial exhaust gases. A method for using the gas purification agent is also provided.
