Abstract
<jats:p>The presence of organic dyes in wastewater is one of the major environmental problems. The textile, food, cosmetic, paper and other industries are the primary sources of water contamination with dyes, which, in turn, gives rise to significant challenges for aquatic lifeforms. This article considers the sorption properties of a porous adsorbent, obtained through the treatment of polyvinyl chloride waste with hydrochloric acid, with respect to xylene orange dye. The experimental data regarding the influence of initial dye concentration on sorption were processed using the Langmuir, Freundlich and Dubinin-Radushkevich models. It was determined that the sorption process is best described by the Langmuir model.</jats:p>
