- Abstract
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 25°C 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.
