چکیده
In this study, Ethinylestradiol was removed from aqueous solution (maximum removal 83.1%) by hydrothermally carbonized and steam activated carbon adsorbent prepared palm kernel shells. The effects of varying mass, pH, temperature concentration on adsorption were studied. It found that pseudo second order kinetic model is able to describe well the Ethinylestradiol. Thermodynamic studies showed process mainly chemisorption as calculated activation energy for 60.4 KJmol?1. Adsorption considered take place between functional groups those molecule. characterization mesoporous with specific surface area 320 m2g?1, it had several oxygen-containing groups, defects in its graphitic structure (ID/IG ratio ? 2.2). Novelty statement: High carbonization temperatures (300°C - 600°C) followed high-temperature (600°C 1000°C) have been used prepare adsorbents over past decades. work, novelty lies lower processing temperatures. Hydrothermal realized at 200°C following 500°C will produce an efficient adsorbent, which shown study. carbonization-activation higher amount beneficial adsorption, decreases costs production.
