Case Study
How Does Ion Exchange Column Work?
When the operation is carried out for a certain period of time, the resin bed will be divided into a saturated resin zone, a mass transfer zone, and a fresh resin zone. As the run time increases, the mass transfer zone gradually decreases until the bottom of the bed is penetrated by the mass transfer zone and the entire resin layer fails.
Basic Type of Ion Exchange Resin
The functional group of the resin determines the properties and uses of the resin.
What is Simultaneous Moving Bed?
The whole section of resin in the original fixed bed is divided into several sections.
What is Ion Exchange?
The ion exchange is a technique for separating using an exchangeable group in an ion exchanger and a difference in ion exchange capacity between various ions in a solution, and is a method of solid-liquid separation.
The Structure of Ion Exchange Resin
The unique properties of ion exchange resins are due to their special internal structure, which is the combination of physical and chemical action.
Basic Characteristics of Ion Exchange Resins
The important physical parameter, such as appearance, particle size, reversible swelling, moisture, density, capacity.
Pretreatment of Ion Exchange Resin
In the production of ion exchange resins, a small amount of organic oligomers and some inorganic impurities are often contained.
IEX Recommended Temperature
The ion exchange resin causes degradation of the functional group and a decrease in the exchange capacity at a certain temperature, so the use of the resin needs to be maintained at a certain temperature as much as possible.
