An adsorbent particular product for treating contaminated liquid

摘要

An adsorbent particular product for treating contaminated liquid is disclosed. The product comprises unexpanded intercalated graphite in particulate form, and is capable of electrochemical regeneration. The particulate form may be powder or flakes. The graphite has been intercalated with a precursor selected from sulfuric acid, phosphoric acid, nitric acid, trifluoroacetic acid and perchloric acid. A method of making a product comprising mixing graphite and the precursor for an intercalating material, placing a body of the mixture between an anode and a cathode, applying a voltage across the anode and the cathode to pass a current therebetween and intercalate the graphite, is also claimed.
