How ion exchange resins work
Ion exchange resin is a kind of high polymer, which contains active groups capable of ion exchange. These active groups can dissociate in water to form charged fixed parts and mobile counter-ions. The working principle of ion exchange resin mainly involves the following aspects:
Ion exchange process
In ion exchange, cations in water (e.g. Na +, Ca² +, K +, Mg² +, Fe³ +, etc.) are exchanged with H + + on a cation exchange resin, and anions in water (Such as chloride ions, bicarbonate and so on) are exchanged with OH on an anion exchange resin. Specific reactions are as follows:
Cation exchange: [R-H^+ + Na^+ \rightarrow R-Na^+ + H^+]
Anion exchange: [R-OH + Cl^- \rightarrow R-Cl + OH^-]
Eventually H plus OH combines to produce water, which in turn removes salt from it.
Regeneration process
After a period of use, the ion exchange resin will adsorb a large number of impurity ions, causing it to lose its exchange ability. At this time, it needs to be regenerated to restore its original composition and performance. The regeneration process is to restore the exchange ability of the failed resin by using a specific chemical agent, such as an acid or base. For example, cationic resins can be regenerated by strong acids such as( HCl orvitriol), while anionic resins can be regenerated by strong bases such as NaOH.
Application field
Ion exchange resin is widely used in water treatment, chemical industry, medicine and other fields. For example, in water treatment, it can be used in the preparation of hard water softening, desalted water, pure water and high pure water; In the chemical field, it can be used as catalyst and dehydrating agent, as well as hydrometallurgy, separation and purification of rare elements.
conclusion
In summary, the ion exchange resin exchanges ions in water through its internal active groups, so as to achieve the purpose of removing salt from water. In the course of use, it needs regular regeneration treatment to restore its exchange capacity. Ion exchange resin has been widely used in many fields because of its high efficiency and stability.
Transportation process: The goods are packed directly in the factory, transported to the logistics center of Tianjin port, and then shipped for transportation.
