Cadmium Uptake by Lignocellulosic Materials: Effect of Lignin Content

Two lignocellulosic materials with different lignin contents (18 and 42 %wt) and pure lignin (PL) were evaluated for their effectiveness in binding cadmium from dilute solutions in various concentrations. Maximum sorption capacities (Xm), determined from equilibrium isotherms by applying the Langmui...
