High grafting density of cyclodextrin polymer for fast removal of aromatic compounds from water

摘要

A side-group beta-cyclodextrin grafted poly(glycidyl methacrylate) (PGMA-g-beta-CD) with grafting density of 92% has been synthesized via facile "click" reaction and atom transfer radical polymerization. The final polymer complexed with 4'-aminoazobenzene-4-sulfonic acid and 1-naphthylamine in water to be precipitated within one minute. The PGMA-g-beta-CD polymer showed great potential in fast removal of aromatic compounds in water treatment.
