Abstract
The present disclosure relates to a method for the removal of organic contaminates from wastewater. The method comprises contacting wastewater comprising water and an organic contaminate with a basic immobilized amine sorbent, where the basic immobilized amine sorbent comprises a polyamine bound to an inorganic support via a linker, such that contacting the wastewater causes at a least a portion of the organic contaminate to bind to the basic immobilized amine sorbent.
