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.



For one application, the fixed bed system is usually operated in single column or two columns in series, plus a column for regeneration.

Chelating Resin

Image
SEPLITE ® Chelating Resin SEPLITE® chelating resin  is ion exchange chelating resins for metals removal, recovery and enrichment. Chelating resins are a class of chelating ion exchange resin   with reactive functional groups that chelate to metal ions. They have the same bead form and polymer matrix as usual ion exchange resin, and the variation in chelating resins arises from the nature of chelating agents linked into a polymer backbone. SEPLITE ® Chelating resins contain a wide range of special functional groups that gives them superior selectivity for specific target metals, Such as SEPLITE®LSC710, which is the iminodiacetic acid bonded in a styrene-divinylbenzene matrix. Other functional groups bound to chelating resins are aminophosphonic acid, thiourea, 2-picolylamine and so on. Chelating resins of ion learning exchange   are almost always used to bind cations, which are found in a big range of metals removal, recovery and enrichment in a dilute solution. Chela

Strong Base Anion Exchange Resin (SBA)

Image
SEPLITE ® Strong Base Anion Exchange Resin The Strong Base Anion Exchange Resin  ( sba resin )  is the type of ion exchange resin with functional group of quaternary ammonium, which is strongly alkaline and dissociates just like NaOH and KOH. In chemical structure, there are two types of strong base anion exchange resin with different alkalinity strengths, Type Ⅰ with a trimethyl ammonium group, Type Ⅱ with a dimethylethanol ammonium group. Type Ⅰ shows a higher alkaline than Type Ⅱ. Compared with type 1 strong base anion, this resin is more suitable for applications needing good rinsing performance and excellent regeneration efficiency. The strong base anion   shows an excellent physical and chemical stability, which is capable of exchanging the different anion under a wide range of pH. The Strong Base Anion Exchange Resin is mainly used in water treatment, to produce high purity demineralized water, making use of the ability to adsorb anions strongly. Typical App
