As a preliminary to detailed kinetic analysis of ion‐exclusion operations a study of the rate of absorption of glycerol from dilute aqueous solution has been made in small fixed beds of ion exchange resin. The resin used was Amberlite IR‐120 (hydrogen form) ranging in size from 0.210 to 1.190 mm., as determined by dry screening. Solution flow rates were varied from 0.45 to 22.20 ml./( Analysis of this problem has shown that the operation of such a process may be described by a simple linear rate equation and the usual transient column material balance relations. It was found that experimental breakthrough data could be well matched with curves predicted by such analysis. Furthermore, three characteristic regions of operation are apparent in which different rate controlling processes may be operating.
