In this study, it was tried to remove Th (IV) radioactive ions in aqueous solution by using Cystoseira barbata. Batch extraction method was applied and pH, contact time and concentration effects were investigated. It was determined that the amount of removal was not affected by pH change. As a result of time effects, it was observed that the biosorption process reached equilibrium with in the first 150 minutes. Langmuir and Freundlich isotherm models were applied and qm value was found to be 39,45 mg/g. The Freundlich isotherm model showed slightly stronger correlation than Langmuir isotherm. SEM and FTIR analysis were performed to find out the changes on the surface of algae loaded with Th (IV) radioactive ions and the groups Th (IV) attached on algae surface.
