Resin 25L Bag

BSR CT-100 is a premium grade, high capacity, sulfonated, polystyrene cation resin supplied in the sodium or hydrogen form as moist, tough, uniform, spherical beads. Ion exchange is the unit operation that allows the separation of dissolved ionic species through their transfer from the liquid phase to a solid exchanger material, where they replace other ions of the same electric sign that, in turn, pass to the liquid phase. In this reversible process, chemical transformations do not take place in the ionic species involved or in the exchanger material, enabling their recovery after the ion exchange. The interest for the applications of the ion exchange lies precisely in the possibility of reusing the exchanger material again and again. In order to do so, the material must previously undergo a regeneration process before recovering its initial conditions.
Most applications of ion exchange aim at removing a particular ionic species from a liquid solution, resulting in their specific separation and concentration in the solid phase. Industrial applications for ion exchange processes are numerous: recovery of metal cations in solution, separation of ion mixtures, purification of liquids, controlled release of a chemical species, salts recovery, etc.
