• We developed an effective process for separating the positional isomers <I>α</I>- and <I>β</I>-naphthyl sulfates, in which a separator carries out the selective hydrolysis of <I>β</I>-naphthyl sulfate into <I>β</I>-naphthol, catalyzed by sulfatase from <I>Helix pomatia</I>, and extraction of the resulting product by an organic solvent.<BR>Separator performance was analyzed theoretically on the basis of the purity and the recovery of each isomer. The analysis elucidated the best separator type, the activity of the membrane-bound sulfatase and the operational conditions for efficient separation of the isomers. Mixtures of various feed compositions were separated by use of a model separator with a porous cellulose membrane of 102 cm<SUP>2</SUP> area in which sulfatase was immobilized by albumin and glutaraldehyde, and decanol was used as a sweep liquid. The experimental results of the purity and the recovery of each set of isomers agreed well with the theoretical predictions.
