Sorption of Pb(II) onto a mixture of algae waste biomass and anion exchanger resin in a packed-bed column

► The sorption of Pb(II) onto algae waste biomass and Purolite A-100 was studied. ► The experiments followed the effect flow rate and initial Pb(II) concentration. ► Column regeneration efficiency reached 98%, when using 0.1 mol L−1 HCl. ► The applicability of biosorbent mixture was tested using synthetic wastewater.
