摘要:
以高铁脱硫渣为原料,采取酸浸、还原反应、离心分离、结晶、合成反应、过滤、干燥等工艺制备出99%以上草酸亚铁晶体.研究了反映剂量、反应温度、加料时间对草酸亚铁纯度的影响,讨论了每个因素的规律性.结果表明:14 g硫酸亚铁溶于15 mL水中,用6 mL氨水预处理,6.5 g草酸溶于25 mL水中,用40 mL无水乙醇预处理,反应温度在40 ℃,加料时间在25~30 min,得到纯度为99%以上、平均粒径为5.0 μm的高纯度超细草酸亚铁.
Abstract:
Using desulfurization slag with high iron as raw material, ferrous oxalate with purity has been made over 99% by acid leaching,reduction reaction,centrifugal separation,purifying,crystallizing,synthesis reaction,filtration and drying. The effects of the dose, temperature and feeding time on the purity of ferrous oxalate were studied,and the regularity of these affecting factors was discussed. The results showed that appropriate leaching conditions are as follows:14 g ferrous sulfate dissolved in 15 mL water, with 6 mL ammonia pretreatment, 6.5 g oxalic acid dissolved in 25 mL water with 40 mL ethanol pretreatment. And then under 40 ℃ and feeding time 25-30 min,we got ferrous oxalate powder with purity of 99.1 %, and average particle size of 5.0 μm.
