The Pb(II) biosorption characteristics of Pseudomonas fluorescens PFC02 biomass was examined as a function of initial pH, contact time and initial metal ion concentration. FTIR spectra showed that the principal functional sites taking part in the sorption process included carboxyl , hydroxyl groups and -CH3 stretching groups, the mechanism analysis showed that the chemical chelating was the main adsorption...
An extracellular biopolymer (PS-2) produced by Pseudomonas fluorescence C-2 was used as an alternative biosorbent to remove toxic Pb(II) metallic ions from aqueous solutions. The prepared biosorbent PS-2 were characterized by FTIR and SEM. The effect of experimental parameters such as pH, dosage of biosorbent , Pb(II) initial concentration and contact time on the adsorption was studied. It was found...
