Abstract

REMOVAL OF FLUORIDE USING TREATED BANANA PEEL IN BATCH REACTOR: KINETICS AND EQUILIBRIUM STUDIES

Tej Pratap Singh and C. B. Majumder*

ABSTRACT

In the present Study we did observed the defluoridation capacity of Treated Banana Peel from industrial waste water in a batch reactor. To find out the best operating conditions for maximum removal of fluoride we did varied various parameters and observed their effects on defluoridation capacity. The effects of time and initial concentration of fluoride on the % removal have been studied. Five kinetic models, the Elovich equation, pseudo second order and first order equations, were selected to follow adsorption process, and Pore diffusion. Pseudo second order equation could be used to describe adsorption of fluoride onto adsorbent. Kinetic parameters like correlation coefficients, rate constant, equilibrium adsorption capacities for each kinetic equation were determine and discussed. The best fitting of kinetic data to Elovich equation and pore diffusion model indicate that pore diffusion plays a vital role in controlling the rate of the reactions.

Keywords: Fluoride, Bio adsorption, Treated Banana Peel, Industrial waste water.
