Abstract
In this study, dry powder of bioadsorbent was prepared from neem tree leaves by crushing the dry leaves and the prepared powder of bioadsorbent was used to remove fluoride from aqueous solutions. The produced bioadsorbent was characterized by measuring their porosities and pore size distributions. The microstructure of the bioadsorbent was examined by scanning electron microscopy (SEM). The resulting activated bioadsorbent was used for removal of fluoride from aqueous solution. The effects of pH, temperature and contact time were investigated. Isotherm studies were carried out and the data were analyzed by Langmuir and Freundlich equations. Two simplified kinetic models were tested to investigate the adsorption mechanism.
