Abstract: Heavy metal pollution from industrial wastewater is a worldwide environmental issue.
Biosorption of heavy metals by using biosorbents derived from various types of biomass has
been shown to be effective for the uptake of heavy metal ions. In this study, biosorbents
derived from the biomass of a group of marine macroalgae were used for the removal and
recovery of heavy metal ions from aqueous solutions. Results indicated that the biosorbents
have high uptake capacities and affinities for a number of heavy metal ions. The uptake
capacities of the biosorbents were in the range of 1.0 to 1.5mmol·g-1 for divalent heavy
metal ions. The kinetics of the uptake process was fast and the process can be used in both
batch and fixed-bed operations. It appears that the biosorption process by using
biosorbents from marine macroalgae can be an efficient and cost effective technology for
the treatment of heavy metal containing wastewater.
