Analysis & Characterization Of Pisum Sativum Peels Carbon (PSPC) Used In The Removal Process Of Defluoridation

Abstract

In this study, physically activated Pisum sativum peels carbon (PSPC) was used to remove excess fluoride ions from an aqueous solution with detailed characterization and experiments. PSPC was found one of the most promising bio-adsorbents in this research process. In this study, group adsorption experiments were analyzed for various parameters such as pH from 2 to 10, dose of Pisum sativum peels carbon (PSPC) ranging from 0.5 to 3.0 g/L, contact time with the used medium from 30 to 720 minutes. The initial fluoride concentration ranged from 2.0-15 mg/L, in this case a particle size of 75-600 µm was chosen for the analysis, moving at 150 rpm. Under optimal conditions of other parameters, the percentage of removal was maximum in the pH range of 7-9. The observed calculated data fitted in the Langmuir isotherm better than the Freundlich isotherm.
