DEFLUORIDATION OF WATER USING TAMARIND (TAMARINDUS INDICA) FRUIT COVER: KINETICS AND EQUILIBRIUM STUDIES
In the present study defluoridation of water was conducted using Tamarind fruit cover (TNFC) as a natural adsorbent in virgin and acid treated forms. Defluoridation of water was studied under batch equilibrium and column flow experimental conditions. The adsorbents were characterized by FTIR, SEM, P...
