摘要

The results obtained from this research indicate that the calculation of capacities is dependent on the total metal and biomass concentration in solution, reaction time and on the type of experimental procedure performed. From the isotherms it was seen that as the concentration of the metal was increased, so did the capacity of the biomass to bind more metal. The batch laboratory saturation experiments produced lower adsorption capacities than the isotherm experiments. Our results suggest that it is up to the researcher to select the method to determine the metal binding capacities. Both methods, adsorption isotherms and batch laboratory saturation capacity experiments, may be correct but they produce different results. It is also well known that the reliability of isotherms outside of the experiment for which they were calculated can be questioned. However, they can still provide insight into the binding process. In all probability, the best way to determine the ability for a biomass sample to bind heavy metals, is to study the biomass under the conditions that they would be used in its commercial application.
