摘要
硫酸和盐酸溶液均可以用来浸出电镀污泥中的铬,硫酸浸出效果优于盐酸。硫酸浸出时,在固液比为1:20,温度(50.0±0.5)℃的条件下可以获得最佳浸出率。
Both sulfuric acid and hydrochloric acid are used to leach chemical sludge. The leachability of sulfuric acid is better than that of hydrochloric acid. The best leachability of the sludge is at a liquid and solid ratio of 20：1 and a temperature of （50.0 ± 0.5）℃.
