KINETICS AND EQUILIBRIUM STUDIES OF FLUORIDE ADSORPTION FROM DRINKING WATER ONTO ALUMINIUM MODIFIED ZEOLITE NA-LSX

Fluoride related health issues such as dental and skeletal fluorosis have become a global concern in recent times.Adsorption is one of the affordable defluoridation techniques.This study reports the potentiometric determination of fluoride adsorbed onto Aluminium modified zeolite Na-LSX (AMZL) from aqueous solution at 25 o C and various experimental conditions: pH (4.5-9), initial fluoride concentrations (3-15 mg/L), adsorbent dosage (2.5-12.5 g/L) and contact time (4-6 days) in a batch system.
