Complexation Separation of Fe~(3+) by EDTA from Dissolved Reaction Product of NaOH Molten Salt with Titanium Slag and Preparation of TiO_2
|
Abstract:
Complexation of ferric ions in acid using EDTA(ethylene diamine tetraacetic acid) as chelating agent from the dissolved reaction products of NaOH molten salt with titanium slag was studied.The effects of EDTA added amount,reaction time,pH and temperature on the extraction rates of Ti4+and Fe3+ were investigated.The results showed that the extraction rate of ferric ions increased with increasing the amount of EDTA,prolonging the reaction time,reducing pH and raising the temperature.Spherical anatase TiO2 par...
