摘要:
以硫铁矿烧渣为原料,采用酸解水浸法制备硫酸铁,并用次氯酸钠氧化法制备高铁酸钾.实验结果表明,硫铁矿烧渣制备硫酸铁溶液的最佳工艺条件为:水跟硫铁矿烧渣的质量比为0.65,质量分数为98%的浓硫酸酸解,在280 ℃下酸解反应1 h,铁的回收率可达78.6%;合成高铁酸钾最佳工艺条件为:在25 ℃时,次氯酸钠质量分数20%,硫酸铁跟氢氧化钠的质量比为0.65,反应时间1.5 h,高铁酸钾的产率可达到73.4%;高铁酸钾溶液最佳的储存方法为:聚乙烯塑料瓶避光保存,并添加稳定剂NaIO4,NaIO4在高铁酸钾溶液中的适宜质量分数为0.10%.
Abstract:
Ferric sulfate was prepared using pyrite cinders as raw material by acid splittingwater extraction method.Then potassium ferrate was produced with ferric sulfate by sodium hypochlorite oxidation method.The results of the preparation of ferric sulfate solution from pyrite cinders showed that the best operation conditions as follows:Under the condition of the weight ratio of water and pyrite cinder was 0.65 and 98% sulfuric acid for acid splitting,the recovery rate of ferrum was 78.6% after reacting 1 hour at 280 ℃.Moreover,the best operation conditions of producing potassium ferrate demonstrated as follows:with 20% of the sodium hypochlorite and 0.65 of the mass ratio between ferric sulfate and sodium hydroxide by weight,the yield of potassium ferrate can reach 73.4% by reacting 1.5 hours at 25 ℃.The best storage way was that avoided light and mixed with 0.10% of NaIO4 as stabilizer in polyethylene plastic bottles.
