| Abstract |
This study was concentrated on the experimentally measurable factors which affect the iron precipitation as Jarosite from ferric sulfate solutions. Of seeding quantity, alkali ions, the pH value and temperature, the seeding addition increased the initial rate of iron precipitation and the pH was found to have the greatest effect on the precipitation reaction. To expedite the precipitation of iron as Jarosite during the reaction, the constant pH value of 1.5 was the most preferable. The experimental rate expression for the iron precipitation as Jarosite was as follows: 1/[Fe]²-1/[Fe]²_0=2Kt The activation energy for the reaction was found to be 18Kcal/mole. |
