摘要
分析了废弃光盘中各金属含量,以NaClO对废弃光盘中银提取的方法,使反射层和盘基分离;再以锌粒还原,提取出单质银,实现了盘基及银的回收利用。
The metal content in waste CD-ROM is analysized.The reflective layer and the base plate of waste CD-ROM are separated by NaClO extraction method.Further,the silver are achieved by reduction of zinc tablets,which achieved recycling of silver plate base and silver.This method is simple and feasible.
