Özet
Basic Yellow ve Basic Blue’ nun aktif karbon üzerine adsorpsiyonu tekli ve ikili bileşenler halinde incelenerek adsorpsiyon hız sabitleri hesaplanmıştır. Denge değerleri Langmuir ve Freundlich eşitliği kullanılarak yorumlanmış ve bu izotermlerin sabitleri herbir boyarmadde için hesaplanmıştır. Giles sınıflandırma sistemine göre adsorpsiyon H tipi olarak bulunmuştur. Ayrıca adsorpsiyona sıcaklığın etkisi incelenmiş ve termodinamik parametreler hesaplanmıştır. Entalpi değişmesinin pozitif değeri adsorpsiyon prosesinin endotermik olduğunu göstermiştir. Serbest enerji değişiminin negatif değerleri adsorpsiyon prosesinin çalışılan sıcaklıklarda kendiliğinden olduğunu göstermiştir. Karışımlardan adsorbe edilen miktarın boyarmaddenin tek başına adsorbe olduğu durumdan daha az olduğu gözlemlenmiştir. Kolon çalışmaları yapılmış ve herbir madde için diğer maddenin varlığında ve yokluğunda kolon kapasiteleri hesaplanmıştır.
The adsorption of basic yellow and basic blue on the activated carbon from single component and binary components was studied. The adsorption rate constant were calculated. The equilibrium results were interpreted by the Langmuir and Freundlich equations and constant of these isotherms were calculated for each dye. It was found that individual mass of dye adsorbed from the mixture has less than that of a single dye in solution. According to the Giles classification, the adsorption isotherm for both dyestuffs was of H type. The effect of temperature on the adsorption was examined and thermodynamics parameters were calculated. The positive value of enthalpy change indicated the endothermic nature of the adsorption process. Negative values of free energy change indicated the spontaneity of the adsorption process. In addition, column studies were performed and capacities of column for each solute in the absence and presence of other solute were calculated.
