[0002] After the PCB is stripped of tin, the spent tin stripping liquid becomes ineffective after repeated use for a period of time, and waste tin stripping liquid is generated. The waste tin stripping liquid contains a large amount of metal compounds such as tin, copper, iron, and some organic matter. The composition is complex, and direct discharge not only affects the environment, but also causes cost loss.
