Abstract本发明公开了一种利用镁法烟气脱硫副产料浆制备碱式硫酸镁晶须的方法。它包括:在搅拌条件下,按照1.0~2.0L/(min·L)的气液比将空气通入镁法烟气脱硫副产料浆中,搅拌反应1~5小时,然后滴加MgO悬浊液调节pH至7.5~8.0,陈化1~2h;将陈化后的反应体系过滤取滤液,然后测定滤液中的镁离子浓度,再按照物质的量比MgO:Mg2+=2~1:1的比例在滤液中加入MgO、加入滤液体积1~5%的增溶剂和滤液体积1~3%的分散诱导剂,在超声作用下分散反应0.5~1h,得超声分散后的悬浊液;将超声分散后的悬浊液于120-200℃条件下进行水热合成12~24h,冷却后经过滤洗涤干燥后获得碱式硫酸镁晶须。
