Özet:

 In this study, the removal of Everzol Yellow 3RS dye by adsorption process was investigated by using Gyttja. The effects of pH 311, contact time 5300 min, adsorbent dose 216 gL, initial concentration 1050 mgL, and temperature 2560C on the adsorption process were investigated. In the adsorption process, 10 gL adsorbent dose, original pH value, 90 minutes contact time, 10 mgL dye concentration, and ambient temperature were determined as the conditions where the maximum removal efficiency 90.96 was achieved. To understand the mechanism of the adsorption process on Gyttja, kinetic and equilibrium models were applied. According to the results obtained from the kinetic and isotherm experiments, the adsorption kinetics for the adsorption of Everzol Yellow 3RS dye onto Gyttja were well described by the pseudo-second-order reaction model and the adsorption equilibrium by the Freundlich isotherm model. This means that the rate-limiting step may be chemisorption rather than diffusion, and both film diffusion and intra-particle diffusion processes are significant. It also showed that the adsorption mechanism is not uniformly distributed and is not limited to a single layer. As a result, it was observed that Gyttja can be used as a potential adsorbent in dyestuff removal.

 Bu çalışmada, Gidya kullanılarak Everzol Yellow 3RS boyar maddesinin adsorpsiyon prosesi ile giderimi araştırılmıştır. Adsorpsiyon sürecine pHın 311, temas süresinin 5300 dakika, adsorban dozunun 216 gL, başlangıç konsantrasyonunun 10-50 mgL ve sıcaklığın 25-60C etkisi incelenmiştir. Adsorpsiyon prosesinde 10 gL adsorbent dozu, orijinal pH değeri, 90 dakika temas süresi, 10 mgL boyar madde konsantrasyonu ve ortam sıcaklığı optimum maksimum giderim veriminin 90.96 sağlandığı koşullar olarak belirlenmiştir. Gidya üzerindeki adsorpsiyon sürecinin mekanizmasını anlamak için kinetik ve denge modelleri uygulanmıştır. Kinetik ve izoterm deneylerinden elde edilen sonuçlara göre, Everzol Yellow 3RS boyar maddesinin Gidya üzerine adsorpsiyonu için adsorpsiyon kinetiği ikinci derece reaksiyon modeli modeli ile adsorpsiyon dengesi ise Freundlich izoterm modeli ile iyi bir şekilde tanımlanmıştır. Bu, hız sınırlayıcı adımın difüzyondan ziyade kemisorpsiyon olabileceği ve hem film difüzyonu hem de parçacık içi difüzyon süreçlerinin kayda değer olduğu anlamına gelmektedir. Ayrıca, adsorpsiyon mekanizmasının düzgün bir dağılım göstermediğini ve tek bir katmanla sınırlı olmadığını göstermiştir. Sonuç olarak, Gidyanın potansiyel bir adsorbent olarak boyar madde gideriminde kullanılabilir olduğu görülmüştür.
