摘　　要：报道了无污染生产溴化锂新工艺，用硫化钡还原溶解在氢溴酸中的游离溴，然后加入与硫化钡等物质的量的硫酸，使溶液中的Ｂａ２＋离子和ＳＯ２－４离子都沉淀完全。新工艺不仅消除了溴蒸气的污染，而且增加了溴化锂的产量。A new process preventing pollution for manufacturing lithium bromide was reported.Bromine solved in hydrobomic acid was reduced with barium sulphide. Both Ba 2+ and SO 4 2- were precipitated completely. The new process not only controlled pollution of bromine vapor,but also increased output of lithium bromide.
