A review on adsorptive removal of dyes from wastewater by hydroxyapatite nanocomposites

This review summarizes compilation of recent literature on the removal of anionic and cationic dye by different hydroxyapatite nanocomposites, comparison of adsorption capacities of different hydroXYapatites, the possible adsorptive mechanism of removal of dyes, the general isotherm, and kinetic and thermodynamic studies explaining the type of Adsorption and the characteristics, advantages, and limitations of adsorbents.
