In this test which is based on the basic aluminum sulfate desorption desulfurization method,the influence of Fe~(2+),Fe~(3+)and Mn~(2+)on catalytic oxidation of S(Ⅳ)and SO_2 desorption rate was investigated.The results show that,when the concentration of Fe~(2+),Fe~(3+)or Mn~(2+)in the solution was higher than0.06mol/L,0.04mol/L or 0.02mol/L respectively,the S(Ⅳ)would be oxidized catalytically into S(Ⅵ),and the higher the ions concentration,the more dramatic the catalytic oxidation effects would be.Thus,the...
