Abstract

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 particles with average diameter of 100 nm could be obtained by hydrolyzing the residues at boiling point, and the content of TiO2 reached up to 99.3%.

Key words: titanium slag, molten salt method, ethylene diamine tetraacetic acid, complexation, titanium dioxide

摘要： 研究了酸性介质中EDTA对高钛渣与NaOH熔盐反应水洗产物中Fe3+的络合作用，考察了EDTA加入量、反应时间、pH值和温度对Ti4+和Fe3+溶出率的影响. 结果表明，增加EDTA量、延长反应时间、减小pH值及升高温度，Fe3+溶出率增大. 将反应后的固相在105℃下水解可制得球状锐钛型TiO2，平均粒径为100 nm，纯度可达99.3%.
