摘　　要：研究了用钡盐脱硫渣制备氢氧化钡。通过单因素试验和正交试验,考察了溶解温度、反应时间、液固体积质量比对硫化钡溶解制备氢氧化钡的影响。结果表明:影响氢氧化钡的因素主次强度为溶解温度>液固体积质量比>反应时间;在溶解温度95℃、反应时间60min、液固体积质量比2.5∶1的最佳条件下,氢氧化钡生成率为98.92%,满足工业化需求。Preparing of barium hydroxide using desulfurization slag of barium salts was investigated . The effect of temperature ,reaction time and the ratio between liquid volume and solid mass on product rate of barium hydroxide were examined by single factor and orthogonal experiments .The results show that the factors according to the significant level are temperature ,the ratio between liquid volumeand solid mass ,reaction time .Under the optimum conditions of temperature of 95℃ ,reaction time of 60 min and the ratio between liquid volume and solid mass of 2 .5∶1 ,the product rate of barium hydroxide reaches 98 .92% ,and meets industrial production requirement .
