Abstract: METAL REMOVAL FROM AQUEOUS SOLUTION USING CASHEW BAGASSE.The metal ions removal on cashew bagasse, a low-cost material, has been studied by batch adsorption.The parameters chemical treatment, particle size, biosorbent concentration, and initial pH were studied.In this study the maximum ions removal was obtained on the cashew bagasse treated with 0.1 mol/L NaOH/3 h, at optimum particle size (20-59 mesh), biosorbent concentration (50 g/L) and initial solution pH 5. The kinetic study indicated that the adsorption metal follows pseudo-second order model for a multielementary system and equilibrium time was achieved in 60 min for all metal ions.
