| Abstract: | One new inorganic poly ferric chloride was prepared from steel rolling acid waste in lab..The results showed that the optimum synthetic conditions were: reaction temperature was controlled at room,mass proportion of Fe2+ in acid waste and oxidant NaClO3 was 1∶0.08,volume of HCl adding in 100 mL acid waste was 17 mL and reaction time was 5 min.The total iron of the prepared PFC is bigger than 40%,the average basicity is 58.7% and the density is 1.3 g/mL. |
