Salvinia natansmacrophyte has been studied as a potential biosorbent for metal ions removal. We investigated in this work the performance of the macrophyte in recovery of lead and chromium from bicomponent synthetic solution from two different systems, batch and fixed bed. Equilibrium data were obtained by batch system through isotherms and fitted toLangmuir and Langmuir-Freundlich models.The breakthrough curves were performed at three different concentrations ratio. In order to know the biosorption mechanism FT-IR analyses were performed for S. natans before and after uptake of metal ions. The results showed different functional groups on the biomass surface and the ability of these groups bind with Cr
