Özet:

 The aim of this study is to investigate the removal of methylene blue from wastewater using natural limonitic laterite. For this purpose, the factors affecting the separation of methylene blue from aqueous solution by the adsorption method were examined. The results showed that the adsorption capacity increased slowly with the increase of contact time, the adsorption capacity decreased with the increase of the adsorbent dosage, and the adsorption capacity of limonitic laterite increased as a result of the increase in the initial concentration of methylene blue. Langmuir isotherm, Freundlich isotherm and Dubinin-Radushkevich isotherm model were applied to experimental data. It was found that the Dubinin-Radushkevich isotherm model best fits the adsorption of methylene blue onto natural limonitic laterite. The adsorption of methylene blue onto natural limonitic laterite was determined to be physical adsorption from the Dubinin-Radushkevich isotherm.

 Bu çalışmanın amacı doğal limonitik laterit kullanılarak atık sulardan metilen mavisinin giderimi araştırmaktır. Bu amaçla adsorpsiyon yöntemi ile metilen mavisi sulu çözeltiden ayırmayı etkileyen faktörler incelenmiştir. Sonuçlar göstermiştir ki kontak süresinin artması ile adsorpsiyon kapasitesi yavaşça artmış, adsorbent dozajının artması ile adsorpsiyon kapasitesi azalmış ve metilen mavisinin başlangıç derişiminin artması sonucu limonitik lateritin adsorpsiyon kapasitesi artmıştır. Langmuir izoterm, Freundlich izoterm ve Dubinin-Radushkevich izoterm modeli deneysel verilere uygulanmıştır. Metilen mavisinin doğal limonitik laterit üzerine adsorpsiyonuna en iyi uyan Dubinin-Radushkevich izoterm modeli olduğu bulunmuştur. Metilen mavisinin doğal limonitik laterit üzerine adsorpsiyonu fiziksel adsorpsiyon olduğu Dubinin-Radushkevich izoterminden belirlenmiştir.
