| Abstract: | The catalytic characters of Fe, Cu, Mn and Co, which are essential for the growth of crops, to the liquid phase oxidation of lean SO2 and absorption with NHs under neutral conditions were investigated. It was observed chat (NH4)2SO4. solutions with concentrations as high as 56(wt%) could be obtained when the absorption efficiency of S02 was higher than 85%. Three kinds of compound fertilizer could be prepared by concentrating the raw solution and the components of the fertilizer accord with the demands of agriculture. |
