Fixed bed column performance of Tinospora cordifolia for defluoridation of water

A continuous adsorption study in a fixed-bed column was carried out by using Tinospora cordifolia as an adsorbent for the removal of fluoride from aqueous solution. The effect of flow rate, influent fluoride concentration and bed depth on the adsorption characteristics of adsorbent was investigated...
