Biosorption process is a promising technology for the removal of heavy metals from industrial wastes and effluents using low-cost and effective biosorbents.
In the present study, adsorption of Pb2+, Cu2+, Fe2+, and Zn2+ onto dried biomass of red seaweed Kappaphycus sp.
was investigated as a function of pH, contact time, initial metal ion concentration, and temperature.
The experimental data were evaluated by four isotherm models (Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich) and four kinetic models (pseudo-first-order, pseudo-second-order, Elovich, and intraparticle diffusion models).
The adsorption process was feasible, spontaneous, and endothermic in nature.
Functional groups in the biomass involved in metal adsorption process were revealed as carboxylic and sulfonic acids and sulfonate by Fourier transform infrared analysis.
A total of nine error functions were applied to validate the models.
We strongly suggest the analysis of error functions for validating adsorption isotherm and kinetic models using linear methods.
The present work shows that the red seaweed Kappaphycus sp.
can be used as a potentially low-cost biosorbent for the removal of heavy metal ions from aqueous solutions.
Further study is warranted to evaluate its feasibility for the removal of heavy metals from the real environment.
