The sorption behaviours of NaOH and NaOC 6 H 65 on quaternary ammonium resin with functional groups of ‐NMe + 4 CI − (hydrophilicity) and ‐NBu + 4 Cl − (lipophilicity) in an aqueous fixed‐bed adsorber were investigated. The types of resins and salts, salt concentration, and operating temperature were evaluated to achieve the optimum sorption conditions. The probability distribution function of the breakthrough curve was employed to describe the sorption system. The parameters of probability distribution function, sorption rate, exchange capability, height of mass‐transfer zone and degree of saturation were also obtained. The effective exchange capacities for hydrophilic resins were found to be smaller than those for lipophilic resins. The sorption capability of NaOC 6 H 5 in the resin was larger than that of NaOH.
