Adsorption and regeneration of expanded graphite modified by CTAB-KBr/H3PO4 for marine oil pollution

Expanded graphite modified by CTAB-KBr/H3PO4 was synthesized via composite intercalation agent of CTAB-KBr and natural flake graphite, followed by the activation of phosphoric acid at low temperature. High removal capability, fast adsorption efficiency, excellent stability and good recycling performance make M-EG an ideal candidate for treating marine oil pollution in practical application.204
