Presence of trace metal pollutants in the aquatic system is a worldwide foremost concern. The present investigation was an attempt to find out novel biosorbent for removal Cadmium(CdII) from contaminated water. leaf Sesbania bispinosa screened as potential Cd(II) removing thirty different natural biomasses by physico-chemical and sorption process characterizations. Biosorption capacity S. determined batch mode biosorption method with functions solution pH, contact time, dose initial concentration. Obtained results were analyzed isotherm kinetic study. exhibited equilibrium uptake 30 minutes. At pH 4, 1 g/L sufficient maximum uptake. Scanning Electron Microscopy (SEM) images Fourier Transform Infrared Spectroscopy (FTIR) spectra confirmed favourable surface characteristics. data also demonstrated that Freundlich (R2=0.998) better fitted model compared Langmuir found be 33.33 mg/g. Suitabilty pseudo second order reaction pathway observed during Most especially, selected ascertained effective multimetals [Cd(II) - 67.51%, Cr(VI) – 40.36%, Pb(II) 100% Cu(II) 59.01%] quaternary aqueous Cd(II), Cr(VI), mixture spent can easily regenerated applying 0.1 M HCl desorbing agent. It, therefore, could concluded leaves S.bispinosa might low-cost environmentally sound treatment
