The evaluation of affection of Methylobacterium extorquens - modified silica fume for adsorption cadmium (II) Ions from aqueous solutions affection

Bu çalışmada, Methylobacterium extorquens ile modifiye edilmiş atık malzeme silis dumanı kullanılarak sulu çözeltilerden kadmiyumun uzaklaştırılması araştırılmıştır. Adsorpsiyon deneyleri pH, temas süresi, sıcaklık ve adsorban dozajının bir fonksiyonu olarak yapılmıştır. Optimum sonuçlar pH 5.0de, 60 dk temas süresinde, 25ºC sıcaklıkta ve 1 mg/mL adsorban dozunda elde edilmiştir. Adsorpsiyon verileri Langmuir ve Freundlich adsorpsiyon modelleri ile korelasyonu göstermektedir. Langmuir adsorpsiyon modelinden elde edilen maksimum adsorpsiyon kapasitesi 166.67 mg/gdır. Elde edilen sonuçlar bakteri modifiye - silis dumanının Cd (II) içeren sulu çözeltilerin iyileştirilmesinde alternatif düşük maliyetli adsorban olarak kullanılabileceğini göstermektedir.

Sulu çözeltilerden cadmiyum (II) iyonlarının adsorpsiyonu için Methylobacterium extorquens - modifiye silis dumanı etkinliğinin değerlendirilmesi

In this present study, it was investigated for adsorbtive removal of cadmium (Cd) ions from aqueous solutions using Methylobacterium extorquens - modified silica fume waste material. Batch adsorption experiments have been performed as a function of pH, contact time, temperature and adsorbent dosage. The optimum results were obtained at pH 5.0, contact time of 60 min, temperature of 25ºC and an adsorbent dose of 1 mg/mL. The adsorption data was correlated with Langmuir and Freundlich adsorption models. The maximum adsorption capacity obtained from Langmuir adsorption model was 166.67 mg/g. The results show that the bacteria - modified silica fume could be used for the treatment of aqueous solutions containing Cd as an alternative low cost adsorbent.
