| Abstract: |
| The precipitation of iron from acidic solution was investigated by means of hydrolysis method and sodium jarosite method respectively. The results show that hydrolysis method is ineffective while sodium jarosite method can remove iron in acidic solution. The precipitation rate of iron is close to 100% and the loss rate of chromium is 7% below in laboratory test the conditions of pH=-0.87, 165 ℃ with addition of seed crystal of sodium jarosite. |
