在球墨铸铁中用铜铁试剂～氯仿萃取分离铁,铜合金中用铜试剂氯仿萃取分离铜、铅及球墨铸铁中用铜试剂～氯仿萃取分离锰时,都有大量废氯仿产生,该废氯仿都可以回收,重新再用,减低成本。回收方法:将废氯仿用等体积的10%氢氧化钠(工业品)溶液分二、三次洗涤,(在玻璃容器中搅拌),使大部分铜 In the ductile iron with copper and iron reagent ~ chloroform extraction separation of iron, copper alloy copper reagent with copper extraction and separation of copper, lead and ductile iron with copper reagent ~ chloroform extraction and separation of manganese, there is a lot of waste chloroform produced, the waste chloroform Can be recycled, reuse, reduce costs. Recycling method: the waste chloroform with an equal volume of 10% sodium hydroxide (industrial) solution was divided into two, three washing, (in a glass container stirred), so that most of the copper
