由废酸洗液回收铁和锌波兰波兹南工业大学化工学院进行的废酸洗液综合利用的研究表明，在每立方分米的酸洗废液中通常含Ｆｅ（２＋）１２６．２２ｇ，含Ｚｎ（２＋）８７．６４ｇ。该学院成功地回收了这些金属，其方法是：向酸洗废液中加Ｈ２Ｏ２，使Ｆｅ（２＋）氧化为Ｆ...
Iron and zinc recovery from waste pickling Research on the comprehensive utilization of waste pickling from the Institute of Chemical Engineering of the Poznan Polytechnic University in Poland showed that the acid pickling waste per cubic deciliter usually contains 126.22 g of Fe (2+) Zn (2+) 87.64g. The Academy successfully recovered these metals by adding H2O2 to pickling waste to oxidize Fe (2+) to F ...
