Who makes ion exchange resin?
Who they are. Mitsubishi Chemical Corporation has been manufacturing ion exchange resins synthetic adsorbents for over 70 years. They have over 200 compositions of separation media for variety of applications in the power, food and beverage, and pharmaceutical industries, among others.
Is DuPont buying ion exchange?
WILMINGTON, Del., June 24, 2021, – DuPont today announced the expansion of its ion exchange resin manufacturing production to address the high global demand for its pharmaceutical products such as excipients and active pharmaceutical ingredients (APIs).
What is IX in water treatment?
Ion exchange (IX) is the reversible interchange of ions between a solid and a liquid such as water. Ion exchange is used in water treatment, including water softening, industrial demineralization, condensate polishing, ultrapure water production, and wastewater treatment.
What is chelating ion exchange resin?
Chelating resins are a class of ion-exchange resins. Their main use is for pre-concentration of metal ions in a dilute solution. Chelating ion-exchange resins are used for brine decalcification in the chlor-alkali industry, the removal of boron from potable water, and the recovery of precious metals in solutions.
What is ion exchange resin made of?
Ion-exchange resins are generally made from methacrylic acid, sulfonated styrene, and divinylbenzene (DVB).
How long does ion exchange resin last?
about 10 to 15 years
As a general rule, you can expect an ion exchange resin to last about 10 to 15 years in water treatment (as opposed to four to eight years for anion exchange resins).
How many types of ion exchange resin are there?
2.1. 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 chelating resin made from?
Chelating resins are styrene-divinylbenzene polymers to which iminodiacetate groups are introduced. This functional group forms complexes with all the metallic elements except the alkali metals, with stabilities that vary with the different metals; in analytical chemistry, they are used…
What are the types of ion exchange resins?
4 Ion Exchange Systems. 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.
Is ion exchange resin hazardous?
Prolonged or repeated contact can cause slight skin irritation. Prolonged or repeated contact can cause slight skin irritation. Can cause irritation.
When should I replace ion exchange resin?
Replace only the resin that has been physically damaged. Such resin should be removed from the ion exchange vessel by careful backwashing, and each time the resin volume has visibly or measurably decreased, the missing resin should be replaced.
