Sr(II) Removal from Aqueous Solution by Bacillus cereus Biomass, Equilibrium and Kinetic Studies

Abstract:

Article Preview

Batch experiments were carried out to determine the capacity of Bacillus cereus biomass to adsorb Sr(II) ions from aqueous solution with respect to pH, initial Sr(II) concentration, contact time and biomass dose. The experimental data were modeled by Langmuir and Freundlich isotherm models. Langmuir model resulted in the best fit of the adsorption data. The maximum adsorption capacity for Sr(II) was 78.34 mg/g. The best correlation was provided by the second-order kinetic model, implying that chemical sorption was the rate-limiting step. The practical implication of this study is the development of an effective and economic technology for Sr(II) removal from contaminated waters.
