Process for removing selenium from selenium-containing waste streams |
摘要 |
A process for removing contaminating levels of selenium from a contaminated aqueous solution is disclosed. That process includes providing a vessel or flow-permissive container containing a water-insoluble polymeric adsorption medium having a plurality of polymerized C1-C4 N-alkylated pyridinium-containing adsorption sites. An influent of an aqueous solution having a total selenium concentration of about 10 to about 1000 parts per billion is introduced to the vessel or flow-permissive container to contact the insoluble polymeric adsorption medium. The solution is maintained in contact with that insoluble adsorption medium for a time period sufficient for the medium to bind the selenium in the contacting solution. The resulting aqueous solution is discharged from the vessel as an effluent having a total selenium concentration whose ratio to the total selenium concentration of the influent is about zero to about 10-3. |
