| Abstract: | This paper is about the study of dephosphorization from silica fume powder by leaching method and experiments are implemented to study the influence of pH value on dephosphorization.The results show that the lower the pH value is,the better the effect of phosphorus removal.This paper focuses on the behavior of phosphorus in removal process and furthermore,the mechanism research is carried out through thermodynamics analysis. |
