Abstract

The rate of exchange of ferric ions from solutions of ferric nitrate and hydrogen ions from Dowex 50X-8 has been studied in an agitated bed ion exchange column over a range of bed loading conditions. Agitation has been maintained in a regime known to indicate film diffusion control of rate in small scale batch reactors.

Calculated diffusion coefficients for the column are slightly higher than those determined in the batch reactor because of greater turbulence of agitation in the column.

The assumption of previous investigators concerning linearity of equilibrium data has been found to be invalid for the system studied. Equilibrium data for the system investigated has been determined and the necessity of accuracy in its determination is discussed.

The relationship between pH, the rate monitoring technique used in these studies, and ferric ion concentration in solution has also been determined and the necessity of this determination is discussed.

A method of constructing predicted concentration-vs-time curves for agitated bed ion exchange columns is presented.
