REMOVAL OF FLUORIDE USING LOW-COST MATERIALS AS ANADSORBENT

Pappu Kumar Yadav and Ajai Singh

Abstract

In the present work, locally available adsorbents such as Sugarcane Bagasse, Coconut Husk and Rice Huskwere tested for defluoridation. The characterizations of the three adsorbents were carried out to study theeffect of pH, different doses of adsorbent and variation in initial concentration of fluoride at constanttemperature of 30±2 °C on removal efficiency of fluoride. It was observed that as the pH value increased,the removal efficiency increased to some time and later became constant in case of Sugarcane Bagasse atadsorbent dose of 0.5g/100 ml at contact time duration of 75 minutes. The removal efficiency decreasedwith gradual increase in initial fluoride concentration due to the capacity of adsorbent materials. The studyrevealed the applicability of low-cost adsorbents for the removal of fluoride from drinking water.
