Citric acid, scientific name 2-hydroxypropane-1,2,3-tricarboxylic acid, is widely used in food, medicine, cosmetics and other industrial fields. The production of citric acid is mainly through biological fermentation. In the process of fermentation, salt, pigment and other impurities will inevitably be produced. It is necessary to achieve the impurity removal and purification of citric acid through necessary refining process to meet the requirements of relevant standards.

There are many kinds of ion exchange resins, the most basic of which is anion cation exchange resins. The application fields of different types of ion-exchange resins are also different. What are the uses of different ion exchange resins? Now, Sunresin will give you a brief explanation.

Ion exchange resin is a kind of macromolecule compound, a kind of macromolecule with the network structure of the functional group. What are the performance and working principle of this kind of polymer? Here, as one of the most professional anion exchange resin manufacturers, we will briefly introduce it to you.

Sunresin, anion exchange resin supplier, gives a plan for ion exchange resin pretreatment. Let's take a look at it.

Ion exchange is one of the most commonly used water treatment technologies.

Water treatment resins are classified into cationic resins and anionic resins. Cationic resins are subdivided into sodium and hydrogen resins. Sodium resins exchange calcium and magnesium ions into sodium ions, which soften water.

Cation resin is a negatively charged matrix with exchangeable positive ions (cations).

The particle size and physical properties of ion exchange resin have a great influence on its performance.
