Abstract: In this research the batch removal of cadmium and lead ions from semi-synthetic wastewater solution using Sargassum sp. was determined. FTIR analysis showed that hydroxyl and carboxyl groups could be very effective for capturing these ions. pH, biomass dosage, contact time and initial concentration that were effective on the bioadsorption process were investigated. And then Langmuir and Freundlich isotherm models were used for the mathematical description equilibrium data. The experimental adsorption data of Cd2+ ions was fitted to the Langmuir isotherm.
