Clays play an important role in the environment. By removing cations and anions either through ion exchange, adsorption and precipitation, or all these combined, they can act as nat - ural decontaminating agents of numerous pollutants. In this study, four modified bentonites (La-, Ce-, Y-, Fe-bentonite) were prepared and characterized, and their phosphate sorption capabilities were measured in batch experiments. Equilibrium times were also examined. The activation energy of the sorp - tion process was calculated. The La- , Ce- and Y-bentonite can bind similar amount of phosphate ions, while iron-bentonite can bind only half of it compared to La-, Ce- and Y-bentonite.
