Abstract
A method is provided for removing metals from a fluid stream containing these metals. The method involves treating the fluid stream with a water soluble ethylene dichloride ammonia polymer having a molecular weight of from 500 to 100,000 that contains at least 5 mole percent of dithiocarbamate salt groups to form a complex with the metals. Then, the fluid stream is passed through a filtering device to remove the complexes from the fluid stream.
