摘　　要：在利用废干电池和钛白厂废硫酸制备锰锌铁氧体过程中,研究了NH4F对脱除硫酸盐溶液中钙、镁的影响。实验结果表明,在反应温度为80℃,pH值为4,反应时间为2 h,加入过量50%的NH4F的条件下,净化后溶液中的钙、镁浓度分别为0.012 g/L、0.053 g/L,达到制备高档锰锌铁氧体产品的要求。This paper studied the influence on removal of calcium and magnesium from Sulfate Solution by NI-hF during the preparation of Mn-Zn ferrite by Waste dry battery and titania plant waste sulfuric acid. The results of experiments showed that the reaction temperature was 90 ℃, pH was 4 and the reaction time was 2h, the NHaF dosage was in excess of 50%, the contents of calcium and magnesium in purified solution were 0. 012 and 0.053 g·L^-1, so the Sulfate Solution was fit to be used to prepare high quality product of Mn-Zn ferrite.
