Adsorption of Anions on Minerals

Natural minerals stand out from conventional materials as promising adsorbents for the anions removal from aqueous solution due to their efficient adsorption performance, cost-effectiveness and easy-availability. This chapter summarizes the advances of natural minerals as adsorbents for the removal of anions (arsenic, phosphorus, fluoride, nitrate) in water. The common natural minerals, as well as their adsorption capacity, are introduced for each anion. The affecting factors and adsorption mechanism are also highlighted.
