The removal of cadmium (II), onto agricultural waste biomass carya shell (CS) over a wide range of reaction conditions was studied from aqueous solution. These conditions including the effect of solution pH, initial concentration, contact time on sorption efficiency. The cadmium (II) adsorption was favored with maximum adsorption at pH 7.0. The uptake amount of cadmium (II) onto CS was increased with...
In the present study we reported the feasibility of Pseudomonas alcaligenes biomass as an alternative biosorbent to remove Pb(II) metallic ions from environmental and industrial wastewater. The ability of Pseudomonas alcaligenes to remove the metallic ions was investigated by using batch biosorption procedure. The effects such as, pH, biosorbent dosage, sorbate concentrations and sorbate-sorbent contact...
The present study was undertaken to evaluate the feasibility of Pseudomonas alcaligenes biomass for the removal of strontium ions from aqueous solutions. Batch experiments were performed to study the adsorption of strontium on pH, Pseudomonas alcaligenes biomass adsorbent with respect to initial Sr(II) concentration, contact time and biomass dose. The experimental data were modeled by Langmuir and...
The Ni(II) biosorption characteristics of Bacillus cereus B-11 biomass was examined as a function of initial pH, contact time and initial metal ion concentration. The pseudo-second-order kinetic model was found to be well suited for the entire adsorption process of Ni(II) on B-11. Langmuir and Freundlich models were applied to describe the biosorption isotherm of the nickel ions by B-11 biomass. Langmuir...
