A new sorbent (raw rice bran) was investigated for heavy metal ions removal from aqueous solutions. Rice bran characterisation was carriedout in order to identify the functional groups possibly involved in the metal binding. The binding process was studied in terms of bindingcapacity and metal affinity. The adsorption equilibrium was well described by the Freundlich isotherm model. The negative Gibbs free energyvalues obtained in this study with rice bran confirm the feasibility of the process and the spontaneous nature of sorption
