Bazik Yellow 51 Boyar Maddesinin Pirinç Kabuğu ve Yanmış Pirinç Kabuğu Kullanılarak Adsorpsiyonunun Kinetik, İzoterm ve Termodinamik İncelemeleri

Öz

Bu çalışmada; pirinç kabuğu ve yanmış pirinç kabuğu (yakılarak aktif karbon formuna getirilmiş) katyonik bir boyar madde olan Bazik Yellow 51(BY51) boyar maddesinin sulu çözeltiden adsorpsiyonla gideriminde düşük maliyetli bir adsorbent olarak kullanılmıştır. Pirinç kabuğu ve yanmış pirinç kabuğunun karakterizasyonu SEM (Scanning Electron Microscope) ve FTIR (Fourier Transform Infrared Spectroscopy) kullanılarak yapılmıştır. Başlangıç boyar madde konsantrasyonu ve temas süresi, pH, sıcaklık dahil olmak üzere tüm operasyonel parametrelerin boyar madde giderim verimi üzerine etkileri incelenmiştir. Tüm çalışmalar kesikli modda yapılmıştır. Adsorpsiyon verileri Langmuir ve Freundlich izoterm modellerine uyarlanarak analizi yapılmış ve tek tabaka adsorpsiyon kapasitesi hesaplanmıştır. Kinetik veriler yalancı birinci ve yalancı ikinci mertebe kinetik modellerine uyarlanmış ve yalancı ikinci mertebe kinetik modeline uyduğu tespit edilmiştir. Entalpi (H°), entropi (S°) ve serbest enerji değişimleri (G°) gibi termodinamik parametreler de incelenmiştir. Serbest enerji değişimi Bazik Yellow 51 boyar madde adsorpsiyonunun pirinç kabuğu ve yanmış pirinç kabuğu için çalışılan tüm sıcaklıklarda kendiğilinden gerçekleşebileceğini göstermiştir. Bu durum da pirinç kabuğu ve vanmış pirinç kabuğunun, sulu çözeltiden katyonik boyar madde giderimi için uygun bir adsorbent olarak kullanılabileceğini göstermiştir.

Kinetics, Isotherm and Thermodynamic Studies of The Adsorption Behavior of Basic Yellow 51 Onto Rice Husk and Burned Rice Husk

Öz

In this work, rice husk and burned rice husk were used as low cost adsorbents to remove a cationic dye, Basic Yellow 51(BY51) , from aqueous solution by adsorption. Characterization of rice husk and burned rice husk was carried out with Scanning Electron Microscope and Fourier Transform Infrared Spectroscopy. The effects of operational parameters on the efficiency of dye removal including initial dye concentration, contact time, pH, and temperature were investigated. All series experiments were carried out in batch mode. Equilibrium data were analyzed using Langmuir and Freundlich isotherm models and monolayer adsorption capacity was calculated. Kinetic data were studied using pseudo first order and pseudo second order kinetic models and dye removal was found to follow the pseudo second order kinetic model closely. Thermodynamic parameters such as enthalpy change (H°), entropy change (S°) and free energy change (G°) were also investigated. Free energy change showed that adsorption of Basic Yellow 51 was spontaneous at all studied temperatures for rice husk and burned rice husk. It is proposed that rice husk and burned rice husk may be suitable as adsorbents for removal of cationic dyes from aqueous solution.
