ion exchange resin - Tedimex

ION-EXCHANGE RESINS
An ion-exchange resin is an insoluble matrix
in the form of small (1–2 mm diameter)
beads, usually white or yellowish, fabricated
from an organic polymer substrate. The
material has highly developed structure of
pores on the surface which are sites where
ions are easily trapped and released. The
trapping of ions takes place only with
simultaneous releasing of other ions, thus
the process is called ion-exchange.
Depending on the application, there are
different types of ion-exchange resin
available. As beads they are widely used in
different separation, purification, and
decontamination processes. The most
common examples are water softening and
water purification.
Water softening
In this application, ion-exchange resins are used to replace the magnesium and calcium
ions found in hard water with sodium ions. When the resin is fresh, it contains sodium ions
at its active sites. When in contact with a solution containing magnesium and calcium ions
(but a low concentration of sodium ions), the magnesium and calcium ions preferentially
migrate out of solution to the active sites on the resin, being replaced in solution by sodium
ions. This process reaches equilibrium with a much lower concentration of magnesium and
calcium ions in solution than was started with.
The resin can be recharged by washing it with a solution containing a high concentration of
sodium ions (e.g. it has large amounts of common salt (NaCl) dissolved in it). The calcium
and magnesium ions migrate off the resin, being replaced by sodium ions from the solution
until a new equilibrium is reached.
Water purification
In this application, ion-exchange resins are used to remove poisonous (e.g. copper) and
heavy metal (e.g. lead or cadmium) ions from solution, replacing them with more innocuous
ions, such as sodium and potassium.
Few ion-exchange resins remove chlorine or organic contaminants from water - this is
usually done by using an activated charcoal filter mixed in with the resin. There are some
ion-exchange resins that do remove organic ions, such as MIEX (magnetic ion-exchange)
resins. Domestic water purification resin is not usually recharged - the resin is discarded
when it can no longer be used.

MB 400
MB 400 resin is a ready for use mixture of powdered cation and anion exchange resins. This
resin is designed to be applied to pre-coat filters to demineralise and filter liquids to a high
degree of purity.
MB 400 resin is the ideal choice for the treatment of neutral or slightly alkaline condensates
and offers the following advantages:
• Total absence of unpleasant smell,
• Highly efficient filtration,
• Cycles usually longer, resulting in less resin consumption,
• Reduction in the volume of spent resin sludge to be destroyed or stored.
MB 400 resin is prepared from resins which have been nearly 100% regenerated with a
high-purity reagent.
