The use of algae to remove zinc and lead from industrial wastewater

The work presents the results of a study whose aim was to compare the assessment of effectiveness of removal of zinc and lead ions from the solution with the participation of two algal populations: Raphidocelis subcapitata cultured in laboratory conditions and a mixed population of chlorophyta coming from a natural water reservoir. The experiment assumed carrying out a model study involving the initiation of the process of biosorption of metal ions with the participation of both populations through dosing the ions of Pb(II) and Zn(II). In the second stage, the process was repeated with the participation of wastewater coming from battery manufacture. The process was controlled by assessing the rate of metal biosorption in comparison to the control sample after the assumed exposure times. The presented results of the study confirm the effectiveness of chlorophyta in the process of zinc and lead biosorption.
