What is ion exchange resin column?
Ion exchange resins are used as the stationary phase in ion exchange chromatography, a separation procedure in which ions of like charges are separated by elution from a column packed with finely divided resin.
What is ion exchange capacity of resin?
Ion exchange resins are used to demineralize water and to separate mixtures of ions. One important characteristic of ion exchange resin is its capacity, expressed in terms of milliequivalents of exchangeable ion per gram of resin. Exchange capacity can be measured by exchanging sodium ion (Na+) for.
How do you choose resin for ion exchange?
(4) a resin shall be chosen according to the ingredients of the impurities in the original water. Such as more organic substances in the original water, or removal of the radius of the ion, should choose the larger diameter of the resin. Try to choose high-strength porous resin.
How does resin ion exchange work?
Put simply, ion exchange is a reversible interchange of charged particles—or ions—with those of like charge. This occurs when ions present on an insoluble IX resin matrix effectively swap places with ions of a similar charge that are present in a surrounding solution.
What is the purpose of an ion exchange column?
Ion-exchange chromatography columns separate and identify compounds based on their ionic or electrostatic interactions. These columns are widely used for the purification of proteins and peptides, as well as nucleic acids.
How do you calculate resin capacity?
The softener capacity is calculated in three simple steps:
- Convert water hardness from ppm to grains per US gallon. Total Hardness (ppm) = Total Hardness (gpg) Example: 118 ppm TH = 6.9 gpg;
- Calculate softener capacity in grains.
- Calculate softener capacity in gallons.
- Table One: Tank Size and Resin Volume.
What is selectivity of resin?
The selectivity coefficient of resins is defined in the ion exchange reactions page. The affinity of the resin for an ion is governed by the size of its hydrated form as well as its charge. The larger the ion, the more the resin bead must expand to accommodate it in the structure.
Why are resins used?
Epoxy resins, also called polyepoxides, are a type of reactive prepolymers and polymers which contain epoxide groups. They have excellent chemical and heat resistance and strong adhesion properties. They are used for laminates, adhesives, flooring, linings, propellers, and surface coatings.
How much resin is in a column?
If you do a regular column, you can buy in the market a 6″ X 48″ column. Fill it to about 30″ height. This gives you about 14 liters of resin. You will exhaust about 4-5 liters per day.
How do you calculate ion exchange capacity?
The IEC is defined as the milliequivalent of ion-exchange groups included in a 1-g dry membrane (meq (g dry membrane)− 1). The concentration of ion-exchange groups is obtained by dividing the IEC with the water content in a 1-g dry membrane (meq (g H2O)− 1).
What are the types of ion-exchange resins?
The four subdivisions are:
- Strong acidic cation exchange resins.
- Weak acidic cation exchange resins.
- Strong basic anion exchange resins.
- Weak basic anion exchange resins.
