ABSTRACT

Fluoride pollution in drinking water is a widespread issue, particularly in regions like Rajasthan, India. Fluoride, a negatively charged contaminant, seeps into water sources through natural geological processes or human activities. Human activities, such as the disposal of industrial wastewater into water bodies, contribute to this problem. To address this issue, a variety of traditional and innovative methods are being employed to remove fluoride from water sources. The review analyzed different adsorbents and their modifications as reported in reputable research publications to evaluate their adsorption capabilities under varying conditions. The impact of additional impurities on the removal of fluoride was also examined. The findings of this comprehensive study indicate that certain adsorbents, particularly binary and trimetal oxides and hydroxides such as alumina, magnesia, and zirconia, show promising potential for effectively removing fluoride from water sources.
