## Abstract Apolar derivatives of polyethylenimine in aqueous solution have been shown previously to bind organic anions very strongly. These studies have been extended to other charged and noncharged small molecules, as well as to derivatives of polyethylβenimine with much reduced positive charge.
Three chemically modified woods were prepared and used for the binding of heavy metal ions. Wood-polyethylenimine composite (wood-PEI) was found to be effective for the adsorption of heavy metal ions such as Hg2+, Cu2+, and other metal ions which tend to form stable ammine complexes. Adsorption of
