Abstract
A styrene–maleic anhydride copolymer is synthesized, modified in the presence of p-sulfoaniline and formaldehyde, and a new polymer adsorbent is obtained and identified by IR spectroscopy. The ionization constants of ionogenic groups in the adsorbent are determined by the potentiometric method. The adsorption and desorption of lead(II) on the obtained adsorbent are investigated, and optimal conditions of preconcentration are determined. An adsorption–photometric procedure for the determination of lead is proposed, including the adsorption preconcentration of lead(II) from a buffer solution with pH 6 and desorption with a solution of HCl (with the desorption rate of up to 99%). The procedure was used to determine lead in the cattle liver.
