Characterization and Adsorption Study using Cocus nucifera midribs for Fluoride Removal

Characterization and Adsorption Study using Cocus nucifera midribs for Fluoride Removal New and cost effective defluoridation method was performed using Pyrolysed Cocos nucifera Midribs (PCM) which is abundantly available and inexpensive raw material from an agricultural tree coconut palm. PCM was characterized both physically and chemically. Effect of pH, dosage of PCM, contact time, initial fluoride ion concentration, temperature and interfering Co-ions were determined using the batch studies. PCM was further characterized by FTIR, SEM studies. Equilibrium data obtained was best fixed to Freundlich isotherm. The sorption nature was studied using thermodynamic parameters Standard free energy change ΔG°, enthalpy change ΔH° and entropy change ΔS°. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

New and cost effective defluoridation method was performed using Pyrolysed Cocos nucifera Midribs (PCM) which is abundantly available and inexpensive raw material from an agricultural tree coconut palm. PCM was characterized both physically and chemically. Effect of pH, dosage of PCM, contact time, initial fluoride ion concentration, temperature and interfering Co-ions were determined using the batch studies. PCM was further characterized by FTIR, SEM studies. Equilibrium data obtained was best fixed to Freundlich isotherm. The sorption nature was studied using thermodynamic parameters Standard free energy change ΔG°, enthalpy change ΔH° and entropy change ΔS°.
