“…The viability of this method is dependent on the development of adsorptive materials. The adsorbents most often used for the removal of fluoride, phosphate, and arsenate are activated alumina (13)(14)(15), activated carbon (16,17), and other materials (18)(19)(20). However, as a result of lower adsorption capacity and poor adsorption kinetic property, these adsorbents cannot be widely used.…”
