What are the properties of ion exchange resin?
Properties of ion exchange resins
- Swelling. Ion exchange resins are hygroscopic.
- Capacity. Capacity is a number of chemical equivalents of ions that can be taken up by a unit amount of the resin (dry weight/wet weight/wet volume).
- Particle size.
- Stability.
What are ion exchange resins classify?
Resin Types. Ion exchange resins are classified as cation exchangers, which have positively charged mobile ions available for exchange, and anion exchangers, whose exchangeable ions are negatively charged. Both anion and cation resins are produced from the same basic organic polymers.
What is resin in ion exchange?
An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
What is the density of ion exchange resin?
560-960 g/l
In the water- swollen state, ion exchange resins typically show a specific gravity of 1.1-1.5. The bulk density as installed in a column includes a normal 35-40 percent voids volume for a spherical product. Bulk densities in the range of 560-960 g/l (35-60 lb/ft3) are typical for wet resinous products.
What are the characteristics of ion exchange resin drug complexes Mcq?
What are the characteristics of ion exchange resin drug complexes? Explanation: Ionisable acidic and basic drugs are complexed with insoluble anion or cation exchange resins. The drug is released slowly by diffusion through the resin particle. Thus the controlled released of the drug is maintained.
What are the types of ion exchange materials?
Ion Exchange Material
- Ion Exchange.
- Zeolite.
- Adsorption.
- Exchangers.
- Resin.
- Exchange Membrane.
- Functional Group.
- Ion Exchanger.
What material of resin is required for ion exchange chromatography?
Resin Selection in Ion Exchange Chromatography Matrices are usually made of cellulose, polystyrene, agarose, and polyacrylamide. Some of the factors affecting resin choice are anion or cation exchanger, flow rate, weak or strong ion exchanger, particle size of the resin, and binding capacity.
Why resin is measured in Litres?
Re: 1kg = a Liter? Only when the density of the liquid is 1.0 (same as water). Resin is a bit more dense, so 1 kg of resin is slightly less than 1 liter of resin.
What kind of material is used in ion exchange chromatography?
Two main groups of materials are used to prepare ion exchange resins: Polystyrene and Cellulose. Resins made from both of these materials differ in their flow properties, ion accessibility and chemicals, and mechanical stability.
What are the types of ion exchange resins?
Ion exchange resins consists of two main types, i.e., cation exchange resins, that exchange positively charged ions, such as sodium, for calcium, and anion exchange resins, that exchange negatively charged ions, such as chloride, for arsenic.
What is the difference between cationic and anionic resins?
As a liquid stream flows through the IX resin, the counter ions can be replaced by ions of a similar charge. Broadly speaking, resins are named for the type of ions they exchange, meaning that cationic resins exchange positively charged ions, while anionic resins exchange negatively charged ions and include:
What are resins and how do they work?
Broadly speaking, resins are named for the type of ions they exchange, meaning that cationic resins exchange positively charged ions, while anionic resins exchange negatively charged ions and include: Now that you know the basics, we’ll explore these resins in greater depth below:
What is weak acid cation exchange resin?
Weak acid cation (WAC) exchange resins remove cations associated with alkalinity (temporary hardness). WAC resins typically employ carboxylic acid functional groups (RCOO –), and are regenerated with sulphuric or hydrochloric acid.
