Only within the past decade has the potential of metal biosorption by biomass materials been well established. Waste crab shell and certain metal-binding algae are found in large quantities in the sea. These biomass serve as a basis for newly developed metal biosorption processes foreseen particularly as a very competitive means for the detoxification of metal-bearing industrial effluents. The assessment of the metal-binding capacity of some new biosorbents is discussed. Biosorption isotherm curves, derived from equilibrium batch sorption experiments and dynamic continuous-flow sorption and...
