Today, I will share with you the knowledge of anion resin, and I will also explain the strong acid anion resin. If it happens to solve the problem you are facing now, don’t forget to pay attention to this site. Let's get started now! List of catalogs in this article: 1. What is the difference between cation exchange resin and anion exchange resin? 2. What ions are adsorbed by anion exchange resin? 3. The synthesis reaction of anion exchange resin? 4. The difference and usage of cation exchange resin and anion exchange resin 5. Cation What is the difference between exchange resins and anion exchange resins? What is the difference between cation exchange resins and anion exchange resins? The difference between cation resins and anion resins. anion exchange. Ion exchange resin is a polymer compound with functional groups (active groups for exchanging ions), network structure and insolubility. The difference between cation exchange resin and anion exchange resin: the functional group of anion resin is a basic group, such as carboxyl-COOH. It is divided into two categories: cationic resin and anionic resin, which can perform ion exchange with cations and anions in the solution respectively. Cationic resins are further divided into strong acidic and weakly acidic, and anionic resins are further divided into strong alkaline and weakly alkaline (or medium strong acid and medium strong alkaline). What ions do anion exchange resins adsorb? 1. Anion exchange resins: The active groups are anions, such as hydroxide ions and chloride ions. The anions in the loading solution are again exchanged for hydroxide or chloride ions to allow the target species to fuse with the resin and be washed away. 2. The anion exchange resin contains a large number of basic groups, such as carboxyl-COOH, and the anion exchange resin dissociates into OH- in water. 3. R-H+Na+→R-Na+H+ R-OH+Cl-→R-Cl+OH- The cation resin can adsorb cations, and the anion resin can adsorb anions. When leaving the factory, the cation resin is generally Na type, which can be directly used for softening, and can be converted into H type if it is regenerated with acid, and used for desalination. 4. The functional group of the anion resin is a basic group, such as carboxyl-COOH. Anion exchange resins can be divided into HO-type resins and CL-type resins according to the ions contained in the functional groups. Through the principle of ion adsorption, the anions in the water are adsorbed, and the anions in the water are removed to make the produced water meet the use requirements. 5. It is alkaline in water, and can exchange anions in the solution for hydroxide or non-metal ions, so the anion exchange resin can absorb tetrahydroxyaluminate. The principle of anion exchange resin is to remove metals and other anions in water or other solutions through self-adsorption, and play a role in purification. Synthesis reaction of anion exchange resin? ②Exchange reaction of anion exchange resin: R+OH-+Na+Cl-R+Cl-+Na+OH-R is a strong polymer base, such as structural formula c. These two reactions are essentially the movement of the chemical equilibrium of the reversible reaction formula (1-1). When there are many Ca2+ and H-type ion exchange resins in the water, the reaction proceeds forward, otherwise, it proceeds reversely. -NH2) or imine group (-NH2) and other basic groups, which are easy to generate OH- ions in water) for exchange of OH-, the anions in the water are transferred to the resin, and the OH- on the resin is exchanged to the water, (That is, the principle of anion exchange resin). The combination of H+ and OH- produces water, so as to achieve the purpose of desalination. Anion exchange resins have the same organic skeleton as cation exchange resins, except that dissociable basic groups, such as -NH, -NH, -NHR, etc., are introduced into the skeleton. If this kind of resin is treated with NaOH solution, an exchange reaction will occur and it will be transformed into -OH type anion exchange resin. The exchange of anions is the same as the above, that is, the anions in the water exchange with the OH- on the material, and the H+ exchanged into the water reacts with the OH- to form water, which will desalinate the solution. During the years of production, our manufacturer has improved the life of the ion exchange resin, allowing people to save costs to a certain extent. The difference and usage of cation exchange resin and anion exchange resin This kind of cation exchange resin is also regenerated with acid (it is easier to regenerate than strong acid resin). Anion exchange resin: Anion exchange resin contains a large number of strong acid groups, such as sulfonic acid group-SO3H, which is easy to dissociate H+ in the solution, so it is strongly acidic. The main difference between cation exchange resin and anion exchange resin is that cation exchange resin mainly adsorbs cations in water, and anion exchange resin mainly adsorbs anions in water. The difference between cation exchange resin and anion exchange resin: the functional group of anion resin is a basic group, such as carboxyl-COOH. The difference between cationic resins and anionic resins: cationic resins can exchange with cations in solution, and anionic resins can exchange with anions in solution. Ion exchange resin is a polymer compound with functional groups (active groups for exchanging ions), network structure and insolubility. Ion exchange resins are divided into two types: yin and yang, cation exchange resins are divided into strong acidity and weak acidity, and anion exchange resins are divided into strong alkalinity and weak alkalinity. According to the nature of the resin group, it is generally divided into cation exchange resin and anion exchange resin, and cation exchange resin is divided into strong acid cation exchange resin and weak acid cation resin, anion exchange resin is divided into strong basic anion resin and weak base Anionic resins. What is the difference between cation exchange resin and anion exchange resin? The difference between cation resin and anion resin: cation resin can exchange with cation in solution, and anion resin can exchange with anion in solution. Ion exchange resin is a polymer compound with functional groups (active groups for exchanging ions), network structure and insolubility. The difference between cation exchange resin and anion exchange resin: the functional group of anion resin is a basic group, such as carboxyl-COOH. It is divided into two categories: cationic resin and anionic resin, which can perform ion exchange with cations and anions in the solution respectively. Cationic resins are further divided into strong acidic and weakly acidic, and anionic resins are further divided into strong alkaline and weakly alkaline (or medium strong acid and medium strong alkaline). Anion exchange resin contains a large number of strong acid groups, such as sulfonic acid group-SO3H, which is easy to dissociate H+ in the solution, so it is strongly acidic. After the resin is dissociated, the negatively charged groups contained in the body, such as SO3-, can adsorb and bind other cations in the solution. Take a small amount of resin, soak it in dilute NaCl solution, and then measure the pH with test paper. Acidic is cation exchange resin, and alkaline is anion exchange resin. This is the end of the introduction of anion resins. Thank you for taking the time to read the content of this site.
