Study of Sorption Properties for Lead(II) Ions Exhibited by Anion Exchangers Synthesized on the Basis of Aromatic Hydrocarbons, Epichlorohydrin, and Polyethyleneimine

Aromatic hydrocarbons, epichlorohydrin, and polyethyleneimine were used to synthesize polyfunctional anion exchangers. IR spectroscopy and elemental analysis were used to examine their composition and structure. The method of classical polarography was employed to examine the process of extraction of lead ions and determine the dependences of the sorption of lead(II) ions in the static mode on the solution acidity, concentration of metal ions, and duration of contact between ion exchangers and a Pb(NO 3 ) 2 solution. It was found that the ion exchangers possess high sorption properties for lead ions.
