Desulfuration by dry process with chemosorbent has become one of the most important methods in industrial desulfurization.High temperature desulfurization requires high energy consumption

while at room temperature desulfurizing agent suffers declined performance.In this study nano-sized ZnO/attapulgite compounds were prepared by co-precipitation using natural attapulgite as a carrier

and calcination at 150℃，250℃，350℃，450℃，550℃

and were characterized with powder X-ray diffraction，scanning electron microscopy and nitrogen adsorption.The samples were used for SO2 removal at room temperature

and the effect of calcination temperature on desulfurizing performance was studied.The result showed that loading of nano-sized ZnO improved the desulfurizing performance of attapulgite.The nano-sized ZnO/attapulgite calcined at 250℃ had the highest capacity.It suggested that the nano-sized ZnO/attapulgite compounds were effective in removing SO2 from indoor air at room temperature.
