Abstract

Sorption properties of porous polymer Dowex L-285, modified by micellar nanoparticles of silver,
were investigated. Net retention volumes were obtained, thermodynamic functions of sorption were
calculated. It is determined, that as a result of modification polymer surface became polar, with capability to
donor-acceptor interactions with alcoholes. It is shown, that long using of obtained adsorbent have
considerable influence for adsorbent properties. Mechanism of micellar nanoparticles of silver adsorption on
the polymer adsorbent surface was suggested. It is determined, that temperature heating on 400 °C lead to
micelle destruction and subsequent increasing of adsorbent affinity with alcoholes
