Abstract

Abstract:

Adsorbent composites comprising of bentonite/sodium lignosulfonate graft-polymerized with acrylamide and maleic anhydride(BLPAMA) were prepared and used to investigate the effect of ionic strength on the adsorption of Pb²⁺ or Cu²⁺ onto BLPAMA in single or binary metal ion solutions, the adsorption isotherms, kinetics and thermodynamics of Pb²⁺ and Cu²⁺ onto BLPAMA with or without addition of 0.2 mol/L NaNO₃ in the binary metal ion solutions. The results show that the increase of ionic strength leads the adsorption capacity of Pb²⁺ or Cu²⁺ to decrease in the single metal ion solution, the adsorption capacity of Pb²⁺ to decrease while the adsorption capacity of Cu²⁺ to increase in the binary metal ion solution.

Key words: lignin, adsorption, ionic strength, additive electrolyte, heavy metal ions
