This study has investigated the adsorption of pesticides onto activated carbon developed from thermal and chemical treatment of waste rubber tire. Chemical treatment prior to activation facilitated in the development of not only a well developed porous adsorbent but also incorporation of carbonyl and hydroxyl functional groups onto the adsorbent surface; these ultimately helped in the adsorption process. Batch adsorption studies revealed maximum adsorption
occurring at a contact time of 60 min, particle adsorbent size of 200-250 mm, low pH and at a lower temperature.
