Abstract

This work investigated the removal of iron ions in fixed bed columns by NaY zeolite at 30°C and pH= 4.5. The experimental breakthrough curves were obtained for feed concentrations from 0.2 to 2.94 meq L-1 and a flow rate of 8 mL min. -1. Through the breakthrough curves it was possible to evaluate isotherm behavior and o obtain the maximum removal capacity of 2.61 meq g-1. Langmuir and Freundlich isotherm models were used to represent the column equilibrium data. A phenomenological model was used to represent the breakthrough curves. The mathematical model was obtained by means of mass-balance equations applied to an element of the column in the liquid phase and solid phase. The overall mass-transfer coefficient was estimated using the experimental data of the breakthrough curves. The mathematical model properly represented the ion exchange of iron ions in fixed bed column.
