FERRONIA ELEFUNTUM FRUIT SHELL : A CARRIER FOR SCAVENGING THE BISMUTH FROM AQUEOUS SOLUTION
The studies on removal of Bismuth were conducted using Ferronia elefuntum Fruit shell. Adsorption efficiency has been evaluated. The effect of pH, contact time, adsorbent dose, concentration of metal, particle size and temperature were studied. The results reveal that Langmuir and Freundlich isotherms are followed during adsorption process. Thermodynamics parameter indicate the feasibility of the process. Kinetic studies have been performed to understand the mechanism of adsorption. Column studies have been carried out to compare these with batch capacities.
