Ions are atoms, or groups of atoms, that bear a positive or negative electric charge. These resin types are available as both strong and weak cation and anion exchangers as well as mixed-bed ion exchangers. A cation is an ion with a positive charge. Types of IX resin regeneration processes The resins are produced in several steps, the two main steps being: Polymerisation of the resin matrix Relying on its own innovation and development, SANYI has developed 12 series and more than 100 varieties of resins with high quanlity, and expanded more and more extensive application fields. 600 mm minimum bed depth for cation / anion components. Instead, we performed a simple experiment in silica polymerization. When in the hydroxide form, SBA resins remove all commonly encountered anions as shown below: As with the cation resins, these reactions are reversible, allowing for the regeneration of the resin with a strong alkali, such as caustic soda, to return the resin to the hydroxide form. EN; Comparison. : 9002-29-3. As the water passes through the resin the resin takes up Ca 2+ and Mg 2+ and releases Na + making for a 'softer' water. ion-exchange-resin. Some hardness or elemental ions are left on and in the resin. It is an insoluble matrix (or support structure) normally in the form of small (0.25-1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. We will examine here the chemical structure of the resin matrix, the functional groups and the overall chemical process or ion exchange resins production. Or are you interested in ion exchange setups and different configurations? A cation resin is one that exchanges positive ions. If the water needs to have the mineral content entirely removed it is passed. In essence, ion exchange is a sorption process and can also be considered a reversible chemical reaction.
