<i>Murraya koenigii </i>(MK) leaf extract was used for the extracellular synthesis of silver nanoparticles (nAg) and the nAg was subsequently employed for the adsorption of fuschin acid dye (FAD). Stable nAg were formed by mixing aqueous solutions of AgCl and MK leaf extracts after few minutes. The synthesized nAg were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), particle induced x-ray emission (PIXE) spectroscopy, UV/visible spectroscopy and fourier transform infrared spectroscopy (FTIR) analysis. Batch adsorption study of FAD was carried out under various experimental conditions: concentration, adsorbent dosage, contact time and pH to evaluate the efficiency of the process. Optimum adsorption of 1.72 mg/g was observed at 60 minutes of contact time with dosage of 2 g at pH of 7.6. The adsorption process increased with increase in initial concentration but decreased with adsorbent dosage. The data were adequately explained by Freunlich and pseudo-second order models for isotherm and kinetics respectively.
