Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In this paper, the effects of various parameters, such as the amount of biomass, pH value, stirring time and culture time, on heavy metals biosorption by P.fluorescens were studied. Meanwhile, the optimal removal condition was obtained by orthogonal experiment, and the heavy metals biosorption were researched. The results showed that heavy metals were adsorbed by P.fluorescens with the order of the adsorption efficiency of Cr>; Pb>; Cu>; Cd. It demonstrated that P.fluorescens was more suitable for handling relatively high concentration wastewater of chromium and lead. For effectiveness, biosorption depends upon selectivity of heavy metals and initial concentration under a constant reaction condition. Compared with the conventional technologies, the method of using P.fluorescens as adsorbents costs less, and has higher removal efficiency.
