Abstract
A systematic study of fixed-bed adsorbers was carried out by using pre-treated biomass of marine alga Durvillaea potatorum as a biosorbent for the removal of copper (II) from aqueous solutions. The effects of particle size, influent concentration, flow rate and column length on the breakthrough curves were investigated. The study indicated that the pre-treated biomass can be used as an efficient biosorbent in fixed-bed operations for the treatment of copper (II) bearing waste water streams. Smaller particles reduced film mass transfer resistances and the intraparticle diffusion paths. Higher influent concentrations resulted in sharper breakthrough curves. A constant pattern breakthrough curve was observed as the column length was of sufficient length.
