Abstract
The adsorptive capacities and potential of biogenic silver nanomaterials of low-cost desert
plant for the removal of basic hazardous dye from its aqueous solution were investigated.
Different techniques were used for the characterization of nanomaterials including UV, FTIR,
SEM-EDX etc. The influence of different parameters on the sorption process was studied using
the batch process to determine the equilibrium sorption capacity of the synthesized
nanomaterials. Kinetic parameters and sorption isotherm models were studied for
determination of kinetic rate and maximum sorption capacity. The equilibrium sorption
capacity of the material increased with increasing the initial dye concentration. The extent of
dye removal decreased with increase in the temperature. The negative values of ∆Go and ∆Ho
indicated the spontaneous, feasible and exothermic nature of the sorption process. The studies
indicated that synthesized nano composites were very attractive material for removing the
selected dye from dyed effluents than many of those reported in the literature.
