Bio-based activated carbon for Cu(II), Ni(II), and Pb(II) ions aqueous sequestration : physiochemical characterization, isotherms, and kinetics

Several biomass waste categories are being used to generate a variety of value-added products due to their natural abundance and low cost. Melia azedarach waste biomass is burned since no industrial application has been identifed. To identify a better utilization, activated carbon was produced from...
