Adsorption studies of fluoride by activated carbon prepared from Mucuna prurines plant

Abstract

Activated carbon synthesized from the plant Mucuna prurines have been successfully used to remove fluoride from aqueous solution by adsorption method. Batch method adsorption has been studied and the adsorption was found to be very significant. Almost 96% of fluoride could be removed by adsorption. Adsorption studies of fluoride signify the fact that among the different adsorption model, Langmuir adsorption model seems to be more favorable in the present case. Different parameters like effect ofadsorbent dosage, contact time, pH and initial concentration are studied to understand the adsorption mechanism.
