Biosorption potential of various waste biomasses for Cu(II) ions removal from aqueous solution

Abstract

In this study, was analyzed the biosorptionpotential of somewaste biomasses in the removal process of Cu(II) ions from aqueous solution. Three types of biosorbents have been used in experiments, namely: marine algae waste,mustard waste and lignin. All these materials are resulted from different industrial activities, and their use for the metal ions removal from aqueous solution is in agreement with the principles of circular economy. The experimental results obtained for the influence of initial Cu(II) ions concentration and contact time on the removal efficiency from aqueous media were modelled using various isotherm and kinetics models. The parameters obtained from modelling have permitted the evaluation of biosorptive potential of these three types of waste biomasses in the removal processes of Cu(II) ions from aqueous solution.
