Optimization of physicochemical parameters used in the removal of zinc and copper from aqueous solutions by the sugarcane bagasse

Abstract The present study was carried out to optimize the various physicochemical parameters (the size of particles of the material, the initial pH of the aqueous solutions, the mass of material used and the equilibrium time) used in the removal of the metal ions of Zn2+ and Cu2+ from aqueous solution by the sugarcane bagasse (SCB). The trading volume for each metal solution is 100 ml. The results show that, for completely purify a metal solution of Cu2+ or Zn2+ of concentration equal to 20ppm by the SCB requires a initial pH equal to 7.2, the diameter (D) of particles of the SCB is of the order 50µm< D
