Adsorption of $Fe^{2+}$ IONS with Saccharomyces cerevisiae immobilized pumice stone

Öz:
Bu çalışmada kolon yöntemi kullanılarak $Fe^{2+}$ iyonlarının Saccharomyces cerevisiae immobilize edilmiş ponza taşına adsorpsiyon şartları araştırıldı. Bu amaçla; adsorpsiyona çözelti pH sının, iyon başlangıç derişiminin ve adsorplanan iyonların geri kazanılması için uygun çözelti türü ve derişiminin etkisi araştırıldı. Maksimum adsorpsiyonun sağlandığı pH değerinin 5 olduğu belirlendi. Optimum pH değerinde, adsorbanın metal tutma kapasitesi 60 $mu g/mL$ başlangıç derişiminde 1,81mg/g dır. Desorpsiyona HC1, NaCl, NH4C1 ve EDTA çözeltilerinin etkisi araştırıldı. En uygun çözeltinin 0,2 M'lık EDTA çözeltisi olduğu gözlendi. 0,2 M EDTA çözeltisi ile %98 oranında desorpsiyon sağlandı.

$Fe^{2+}$ iyonlarının Saccharomyces cerevisiae immobilize edilmiş ponza taşı ile adsorpsiyonu

Öz:
In this study, the adsorption conditions of $Fe^{2+}$ ions on Saccharomyces cerevisae immobilized pumice stone were investigated by column method. In order to perform this aim, the effect of solution pH value, initial concentration of ions and suitable solution and concentration for recovery of adsorbed ions were investigated. At pH 5, the maximum adsorption was obtained. At optimal pH value, adsorption capacity of sorbent for metal was obtained as 1,81 $mg.g^{-1}$, when initial concentration was 60 $mg.ml^{-1}$. Influence of HC1, NaCl, NH4Cl and EDTA solutions on desorption were investigated and maximum recovery was achieved by 0,2 M EDTA solution. Desorption were 98% level provided by 0,2 M EDTA solution.
