摘要
通过在CODcr废液中加入盐酸生成氯化银沉淀,然后将得到的氯化银固体用一定量的浓硫酸加热溶解,生成的硫酸银溶液直接用作催化剂,使CODcr废液中的硫酸银得到回收利用,既有效地节省成本,又减少二次污染。
The silver chloride deposition was generated by adding hydrochloric acid into CODcr waste liquid. And the silver sulfate solution, which was generated by the silver chloride heated to dissolve with a certain amount of concentrated sulfuric acid, was directly used as the catalyst. The silver sulfate in CODcr waste liquid was recycled, so the cost can he partly saved and secondary pollution can he reduced.
