What is the purpose of chelating resins?
The purpose of chelating resins is to provide superior selectivity for specific target ions in challenging separations.
How do chelating resins work differently from ion exchange resins?
Chelating resins form strong complexes with the target ion and the functional groups on the resin, whereas ion exchange resins exchange ions.
How can chelating resins be regenerated?
Chelating resins can be regenerated by disrupting the complex formation or by using a competing ligand that is more favorable than the resin functional group.
In what applications are chelating resins commonly used?
Chelating resins are commonly used in metal removal and recovery applications, including the primary recovery of precious metals and the removal of impurities in high purity processes.
What is brine decalcification in the chlor-alkali industry?
Brine decalcification refers to the process of removing calcium from brine in the chlor-alkali industry using chelating ion exchange resins.
What is resin-in-pulp (RIP)?
Resin-in-pulp is a method for capturing base metals such as copper, nickel, cobalt, and zinc using chelating ion exchange resins.
What is the application of chelating resins in the removal of hexavalent chromium?
Specific chelating resins can be used to remove hexavalent chromium from potable water.
What is the application of chelating resins in the removal of boron?
Specific chelating resins are used to remove boron in semiconductor process water.
What is one application of chelating resins in the recovery of precious metals?
Specific chelating resins are used for the recovery of high-value precious metal catalysts.
Can chelating resins be used to remove mercury?
Yes, specific chelating resins can be used for the removal of mercury, whether regenerable or non-regenerable.
