Studies on the sorption of As(III) on the synthetic gel sodium potassium fluorophlogopite.

Sorption of As(III) has been studied on the synthesized gel close to Sodium potassium fluorophlogopite [Na0.5K0.5Mg3 (Si3 AlO10) F2] as a function of initial solution concentration at pH 2,4 and 7. The effect of parameters like equilibration time (0.5 - 24.0 hr), weight of the exchanger (30-150 mg) and temperature (25 degrees - 45 degrees c) has been investigated. The uptake of metal ion, As(III) has been expressed in terms of distribution coefficient i.e. (kd) values.
