Bio-sorption of Pb2+ ion from wastewater with Chlorella was investigated in the batch mode. The influence of pH of the solution, biosorbents dose, concentration of ions and contact time on bio-sorption capacity of Pb2+ ions was studied. The studies revealed that Pb2+ ions uptake rate was rather slow, with 75% of the total amount occurring in the first 10min for Chlorella. The optimum pH for bio-sorption...
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...
The biosorption of Pb(II) ions on dried wasted beer yeast was investigated with respect to the adsorption conditions. The results of this study indicated that different variables, such as contact time, adsorbent dose, solution pH and initial heavy metal ions concentration influenced the adsorptive quantity. The best adsorption parameters and quantitative analysis of Pb2+ by dried waste beer yeast...
