Abstract

In this study, methylene blue (MB) dye in aqueous solution was tried to be removed by using modified Cystoseira barbata (with 0.1M HNO3 and 1M HNO3). The effects of pH, contact time and different MB concentrations on adsorption were investigated. The results showed that the system reached to equilibrium in the first 50min and pH had no significant effect on adsorption capacity. In the isotherm studies, the Freundlich isotherm model was found to be more suitable and the qmax value was higher in the 0,1M HNO3 group (100.6mg/g). The changes in the algae surface caused by MB and the groups on the algae surface that the dye attached were determined in SEM and FTIR analysis.

Özet

Bu çalışmada, sulu çözeltide bulunan metilen mavisi (MM) boyar maddesinin modifiye edilmiş (0,1M HNO3 ve 1M HNO3 ile) Cystoseira barbata kullanılarak giderilmesine çalışılmıştır. Adsorpsiyona, pH’ın, temas süresinin, farklı derişimlerde bulunan MM çözeltisinin etkileri incelenmiştir. Çalışma sonucunda, ilk 50dk. içerisinde sistemin dengeye geldiği ve adsorpsiyon kapasitesinin pH değişiminden pek etkilenmediği gözlemlenmiştir. Yapılan izoterm çalışmalarında ise, Freundlich izoterm modeline daha çok uyduğu belirlenmiş ve qmax değeri 0,1M HNO3 grubunda daha yüksek (100,6mg/g) bulunmuştur. Yapılan SEM ve FTIR analizlerinde ise, MM boyar maddesinin alg yüzeyinde meydana getirdiği değişikler ve alg yüzeyinde hangi gruplara tutunduğu belirlenmiştir.
