ABSTRACT
Background and aims: Biosorption is an emerging technology for removal of heavy metals from industrial wastewater. The major advantages of this technique are the reusability of biomaterial, low operating cost, improved selectivity for specific metals of interest, short operation time and no production of secondary compounds which might be toxic. Therefore, the aims of this study were to biosorption of copper (II) from aqueous environments by brown algae Padina sp. and Colpomenia sp. in a batch system. 
Methods: Freundlich, Langmuir, Freundlich-Langmuir, and Redlich-Peterson models were applied to describe the biosorption isotherm of copper (II) from aqueous environments by Padina sp. and Colpomenia sp.biomass. Moreover, isotherm experiments were conducted in initial ion concentrations 0.05-5 mm. 
Results: The isotherm dataof copper (II) biosorption by both Padina sp. and Colpomenia sp. were found to be in the best fitness with the Redlich-Peterson equation (R2> 0.986). According to the Langmuir model, the maximum uptake capacities (qm) of copper (II) by Padina sp. and Colpomenia sp. were determined to be 1.06 and 0.97 mm, respectively. 
Conclusion: This investigation indicated that the studied algae had a high potential for full scale application for removal of copper (II) from industrial wastewater.
Keywords: Biosorption, Copper (II), Padina sp. Colpomenia sp, Isotherm
