Bentonite clay is actually a type of clay that is formed by the action of water on the mineral bentonite. In other words, bentonite clay works best when it is mixed with water . Although bentonite clay can be used in many applications and is a very effective product, it is most effective when it is combined with other materials.

Ti(OH)4 and TiCl4 modified bentonite (Ti–Na-bent) were applied in the removal of Th(IV) from aqueous solution. Effect of different factors such as pH, contact time, temperature, initial concentration of Th(IV) and efficiency of them for thorium adsorption are investigated. Ti–Na-bent showed high adsorption capacity (qm = 231.37 mg/g) and quick adsorption kinetics at lower pH. The
