Defluoridation of water using calcium aluminate material
Original language description
A new calcium aluminate (CA) type material has been synthesized using combustion method, which offers formation of smaller particles with open pores. The material thus synthesized has been studied for its fluoride uptake properties in simulated and actual drinking waters, containing fluoride as well as other co-anions. The adsorbent shows high adsorption capacity for fluoride and it is possible to effectively remove fluoride to the tune of 85% from initial concentration of 8.9 mg L-1 and using a dose of3 g L-1. Kinetics of the adsorption system has been studied indicating that the intra-particle diffusion contributes to the rate determining step. The experimental data fitted well into Langmuir adsorption isotherm and follows pseudo-second-order kinetics. The thermodynamic parameters suggest the complex nature of fluoride uptake reaction, dominated by chemisorption. These studies also infer that fluoride adsorption on CA is spontaneous and an endothermic process. The effective regenera
