The use of chlorination for the removal of iron and titanium from clay minerals, and particularly kaolin, has given excellent results. In these processes, high temperatures (700 to 1000 °C) are used, at which the dehydroxylation of kaolinite has already taken place giving as products metakaolinite, and, at higher temperatures, spinell and

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

Syafalni and coworkers observed that bentonite was a good adsorbent for removal of organic matter as evidenced by removal of about 75% chemical oxygen demand (COD) under acidic conditions. The authors further noted that a combination of bentonite with limestone improved the adsorption capacity of the composite bentonite [22] .
