摘要： A mixture of anion and cation exchange resins is separated into their respective resin types by classifying the resin mixture, using a fluid such as water, in the presence of a solid, inert material (e.g., copolymer beads of styrene, divinylbenzene and methyl methacrylate) which, upon classification, forms a layer intermediate between the layers of the anion and cation resins. The degree of resin separation and the location of the layers of the classified anion resin and cation resin are determined by measuring a conductivity property of the resulting classified resin bed.
