In industries such as thermal power plants, petroleum and chemical industries, microelectronics, nuclear, food and pharmaceutical industries, all require water close to the quality of distilled water. With the rapid development of industrial technology, not only the amount of water is increasing rapidly, but also the requirements for water quality are constantly increasing. So far, the ion exchang...

(1) The cation exchanger is located in front of the anion exchanger. The reasons are as follows: a. the exchange capacity of strong base anion exchange resin is low, and the ion exchange reaction efficiency of strong base anion resin in acidic water (H-type cation resin exchange water) is high, and the working exchange capacity can be fully utilized. b. After the raw water is exchanged by H-type c...

In addition to conventional ion exchange resins, micron fine-grained ion exchange resins are also developing rapidly. This kind of resin is mainly used for chromatographic separation. Therefore, a sufficiently small particle size (100~400 mesh) and a relatively narrow particle size distribution are key technical indicators. Suspension polymerization can prepare spheres with diameters ranging from ...

When the macroporous ion exchange resins is used as a porogen in a bad solvent, the properties, dosage and crosslinking degree of the porogen have significant effects on the pore structure of the copolymer. With the increase of the amount of divinylbenzene and pore forming agent, the phase separation appeared earlier and the gel point also appeared earlier. The separated macromolecular chains are ...

(1) Strong acid cation resin This kind of resin contains a large number of strong acidic groups, such as sulfo SO3H, which is easy to dissociate H+in solution, so it is strongly acidic. After the resin is dissociated, the negative group contained in the body, such as SO3 -, can adsorb other cations in the bound solution. These two reactions make the H+in the resin exchange with the cation in the s...

The specific operations are as follows: Clean the bed and put water 1-2 meters deep (ensure that the water surface is higher than the resin layer): 1. The design height shall be filled with resin (the final height of resin shall be subject to re ecology). 2. After installing the cation exchange resin, backwash to make the resin surface smooth, and then install the anion exchange resin; Two steps h...

Ion exchange resins are used in the food industry for a variety of applications. They can be used to remove heavy metals, salts, and other impurities from food products. They can also be used to separate components of food products such as proteins, carbohydrates, and fats. Additionally, Strong acid cation exchange resin and weak base anion exchange resins can be used to adjust the pH of food prod...

Ion exchange resins have been developed in the United States since the 1950s. Early research focused on developing cation exchange resins for water softening and deionization applications. The first commercial ion exchange resin was introduced in 1956 by Dow Chemical Company. Since then, ion exchange resins have been used in a variety of applications, including water treatment, food processing, ph...
