    Abstract: Selenium compounds present in aqueous liquids can be removed using a poly dithiocarbamate materials. The selenium compounds are then removed by precipitation or sedimentation. Optionally, an oxidizing agent may be added to the system prior to the addition of the poly dithiocarbamate. Various filtration methods may be employed to remove the selenium-dithiocarbamate materials from aqueous liquids.
