Biosorption capacity of Lonchocarpus laxiflorus Leaves biomass for adsorption of metal ions ( Fe 3 + , Pb 2 + , Cr 2 + , Cd 2 + and Ni 2 + ) from aqueous solution

The adsorption capacity of Lonchocarpus laxiflorus leave (LLL) biomass for the removal of metal ions (Fe Pb, Cr, Cd and Ni) was investigated and the residual metal ion concentrations was studied using Atomic Absorption Spectrophotormeter (AAS). The adsorption capacity was performed by batch experiments as a function of experimental parameters like effect of pH, contact time, initial metal ion concentration and temperature on biosorpttion of metal ions from aqueous solution. The metal ion sorption capacity by Lonchocarpus laxiflorus increases with increase metal ions concentration. The biomass sorption capacity increases, with increases in pH, reaches a maximum and then decreases steadily. The sorption rate was rapid for the first 30 – 40 min and equilibrium was reached within 120 min. The maximum sorption capacity for Fe Pb, Cr, Cd and Ni was found to be 61, 99, 98,85 and 100 % respectively. The results from these studies will be useful for removal of toxic metal ions from waste water and can be adopted for secondary treatment. It can also be turned into an environmentally friendly and cost effective sorbent for waste water.
