Utilization of a Novel Extracellular Biopolymer Produced from Bacillus cereus B-11 for the Biosorption of Cd(II) from Aqueous Phase

Abstract:

The study described the sorption of Cd(II) by a novel extracellular biopolymer (B-11) produced from Bacillus cereus B-11. The effect of experimental parameters such as pH, initial concentration and contact time, sorbent dosage on the sorption was studied. The langmuir isotherm better fitted the sorption data, the maximum adsorption capacity was 80.64 mg.g^-1. The kinetic rates were best fitted to the pseudo-second-order model. It was concluded that the prepared B-11 can be used as an effective and environmentally friendly biosorbent for the removal of Cd(II) ions from aqueous solution.
