Cation-exchange resin has a variety of uses in automotive manufacturing and construction; it contains negatively charged radicals that attracts and isolates cations. It is also called a cation deionization resin or water softening resin.

What do dowex 50 resins do?
"Dowex 50" is a type of ion-exchange resin, called a strongly acidic cation exchanger, used for ion-exchange chromatography. It is useful for swapping a metal cation for a proton (eg. Na+ for H+) or one metal cation for another (eg. K+ for Na+). This can be an important way for purifying amino acids, carboxylate salts or removing unwanted metal ions from water solutions.

Ion exchange method for the separation of lanthanides?
although the chemical behaviour of all lanthanide ions are almost identical there are slight quantative differences which vary systematically from la to lu . The hydrated radii of ln ions for instance with increase in the atomic number . It is found that the larger the hydrated radius of the ion the less strongly it is bound to the anionic site of an exchange resin . When a solution containing several lanthanides pass slowly through a column of a cation exchange resin the heavier members come through first . The separation can be enhanced by the use of complexing agents like citricacid or citrates. a cation exchange rein like dowex-1 is normally used for adsorption of lanthanide ions . The column is eluted with EDTA . The lanthanides are eluted in the reverse order of their atomic numbers . Polycarboxylates,lactates,hydroxy butyrate and alpha hydroxy carboxylates also can be used as elements . ion exchange method has been used for separation of lanthanides in kilogram quantities for commercial uses
What is an acaroid resin?
An acaroid resin is a resin used in varnishes and lacquer, obtained from plants of the genus Xanthorrhoea.
What is the name of the resin used in urenium extraction?
give the chemical formula ,composition of that resin.
What is an ion exchange resin used for?
Ion exchange resin is used in separation, purifying and decontamination processes. The resin is an insoluble matrix. They are usually made of cross-linked polystyrene molecules.

What is the importance of soil colloids in soil fertility?
Soil colloids have large surface areas which can be used as sights for cation exchange, increasing the soils cation exchange capacity. The higher the cation exchange capacity in a soil, the more the soil is able to retain nutrients because the cations are suspended in the soil and are then able to be used by organisms in the soil.

What ion exchange resin is cheaper and mostly used for anion determination?
your question is too vauge for a proper response. ion exchange resins are designed for a specific purpose....to take out minerals, acids, color, etc..... also the charge of the media being anion or cation and the form.. cloride or hydroxide play a major part in picking a product for use...specify what you wish to accomplish with the resin. there are hundreds of resins.
What is the use of earthen pot in MFC?
It is used as an alternative to cation exchange membrane.
How indicator ion exchange resin made?

Which catalyst is used in any esterification?
An acid catalyst is used can be in many forms such as sulfuric acid or ion-exchange resin.
How do you use the word cation in a sentence?
Appreciate that cation exchange is of importance in the natural environment.

What should be the feed pH to two bed demineralisation plant?
It depends upon which ion exchange system comes first. Anion exchange resin beads are alkaline, because they absorb anions like carbonate and sulphate and replace them with hydroxide, OH-. So it needs an alkaline pH, although not too high. Cation exchange replaces sodium, calcium, magnesium etc with hydrogen ions H+ , so its resin beads will have an acidic reaction and the water should not be alkaline, preferably neutral.
Why demin water water PH kept high?
It is normaly due to sodium leakgae out of the cation resin bed .
