In this study biosorption of Methylene Blue dye on to natural and activated with 1% H2SO4 solution anaerobic sludge
as biosorbent was investigated in batch experiments. Particule size of biosorbent was chosen between 0.125-0.063 mm.
Experimental parameters affected biosorption process such as concentration of dye, contact time, amount of biosorbent,
solution pH and temperature were studied. Langmuir, Freundlich and Dubinin-Radushkevich (D-R) adsorption isotherm
modells fitted to experimental data. Adsorption capacity (Qo) of natural and activated anaerobic sludge as biosorbent for
Methylene Blue dye biosorption was found to be 22.27 and 4.70 mg/g, respectively. For both biosorption studies, biosorption
kinetic was pseudo-second order. Both studies were exothermic based on calculation of thermodynamic parameters (ΔH, ΔG
ve ΔS) and first biosorption (natural anaerobic sludge) study was found to be spontone. As a conclusion; the ose of anaerobic
sludge for color removal from aqueous solutions taken from wastewater treatment plant is important for reuse of them.

DOĞAL VE AKTİFLEŞTİRİLMİŞ ANAEROBİK ÇAMUR KULLANILARAK METİLEN MAVİ BOYASININ BİYOSORPSİYONU: DENGE, KİNETİK VE TERMODİNAMİK ÇALIŞMALAR

Öz

Bu çalışmada, doğal ve % 1’lik H2SO4 çözeltisi ile aktifleştirilmiş anaerobik çamur biyosorbent olarak kullanılarak, kesikli deneylerle metilen mavi boyasının biyosorpsiyonu incelenmiştir. Biyosorbentin partikül büyüklüğü 0.125-0.063 mm arasında seçilmiştir. Boya konsantrasyonu, temas süresi, biyosorbent miktarı, çözelti pH’ı ve sıcaklık gibi biyosorpsiyon prosesini etkileyen deneysel parametreler çalışılmış, Langmuir, Freundlich ve Dubinin-Radushkevich (D-R) adsorpsiyon izoterm modelleri uygulanmıştır. Metilen mavi boyasının biyosorpsiyonu için doğal ve aktifleştirilmiş anaerobik çamur biyosorbentlerinin adsorpsiyon kapasitesi (Qo) sırasıyla 22.27 ve 4.70 mg/g olarak hesaplanmıştır. Her iki biyosorpsiyon çalışmasında da biyosorpsiyon kinetiğinin yalancı ikinci derece kinetiğine uyum sağladığı bulunmuştur. 25-45 oC sıcaklık aralığında yapılan termodinamik parametrelerin hesaplamalarından (ΔH, ΔG ve ΔS) her iki çalışmanın da ekzotermik olduğu, doğal anaerobik çamur kullanılarak yapılan biyosorpsiyonun spontane olduğu belirlenmiştir. Sonuç olarak; atıksu arıtma tesisinden temin edilen bu materyalin bu çalışmada olduğu gibi sulu ortamlardan renk gideriminde başarıyla kullanılabilmesi, atıkların yeniden kullanımı açısından oldukça önemlidir
