Abstract
Provided are compositions for removal of a target substance from a fluid stream, the composition comprising a polyamine; and a covalently linked hydrophobic group, wherein the polyamine is covalently linked to a support material. Also provided are processes for removal of a target substance from a fluid stream comprising contacting the fluid stream with a composition comprising a polyamine; and a covalently linked hydrophobic group, wherein the polyamine is covalently linked to a support material.
Claims22
A composition for removal of a contaminant from an aqueous fluid stream, wherein the composition comprises:
- a) a support material which is at least one of porous, solid, and particulate;
- and
- b) a sorbent molecule comprising:
- i) a branched polyamine covalently linked to the support material;
- and
- ii) a hydrophobic group covalently linked to the branched polyamine.
A method of removing a contaminant from an aqueous fluid stream the method comprising contacting the aqueous fluid stream with a composition comprising:
- a) a sorbent molecule comprising:
- i) at least a branched polyethylenimine (PEI);
- and
- ii) a hydrophobic group covalently linked to the branched PEI.
