Abstract

Low-cost adsorbents, synthesized by pyrolysis of waste rubber (CR) and activated with KOH (CRA), have shown the high removal ability of from aqueous solutions in wide range of pHs (2-10) with fast adsorption rate. The Langmuir and Freundlich models suggests monolayer and multilayer adsorption of onto CR and CRA surface, respectively. The removal mechanism of from solution occurs by replacement with OH- from surface groups (phenolic and/or accompanying carboxylic) of CR and CRA indicating anion exchange mechanism.
