Abstract

Coconut Shell : A Carrier for the Removal of Bismuth from Aqueous Solution

Author(s): U. E. Chaudhari

The studies on removal of bismuth (III) were conducted using coconut 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 parameters 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
