| dc.description.abstract | ABSTRACT: Activated carbon is one of the most important industrial products due to its versatile applications. In this work, efficient activated carbon was produced and utilized for adsorption of nickel from simulated wastewater under varying operational parameters. The raw material (Artichoke) has been chemically modified by zinc chloride (ZnCl2) to improve its surface reactivity and enhance its adsorption capacity. The adsorbent was characterized by the FTIR analysis. The experimental data were analyzed by adsorption isotherms and kinetic models. Langmuir equation proved to be suitable to explain the adsorption process and the experimental results fit well with the pseudo-second-order model. The performance of the prepared artichoke-based activated carbon (AAC) suggests it can be used as low coast or cheap adsorbent for the treatment of water and removal of heavy metal ions from industrial effluents. Keywords: Heavy metal ions, nickel, Activated carbon, Artichoke. ………………………………………………………………………………………………………………………… ÖZ: Aktif karbon önemli bir sanayi ürünü olarak çok çeşitli alanlarda kullanılmaktadır. Bu çalışmada, yapay atık sulardan etkili bir şekilde nikeli arındırmakta kullanılmak üzere aktif karbon üretilmiş ve değişik şartlarda denenmiştir. Hammaddesi enginar olan aktif karbonun yüzeyi çinko klorür (ZnCl2) ile değiştirilerek reaktivitesi ve tutma kapasitesinin arttırılmaya çalışılmıştır. Yüzey tutucu madde FTIR analiziyle karakterize edildi. Deneylerden elde edilen veriler tutma izotermleri ve kinetik modeller ile analiz edilmiştir. Langmuir denklemi tutma sürecini uygun bir şekilde açıklamaktadır ve deneysel sonuçlar pseudo-ikinci dereceden kinetik modeli ile uyumludur. Enginardan hazırlanan bu aktif karbonun (AAC) performansı bu malzemenin düşük masraflı ve ucuz, atık sulardan ağır metal iyonlarının arındırılmasında kullanılabilecek bir tutucu olduğuna işaret etmektedir. Anahtar kelimeler: Ağır metal iyonları, nikel, Aktif karbon, enginar. | en_US |
