Abstract

Methods of stabilizing virgin ion exchange resin material are provided. The methods include rinsing virgin ion exchange resin material with deoxygenated water, introducing the rinsed virgin ion exchange resin material into a liquid impermeable compartment of a gas impermeable vessel and hermetically sealing the vessel. The methods include rinsing virgin ion exchange resin material with deoxygenated water, introducing the rinsed virgin ion exchange resin material into a gas impermeable vessel, introducing an oxygen scavenging material into the gas impermeable vessel, and hermetically sealing the vessel. A method of facilitating water treatment in a site in need thereof by providing rinsed virgin ion exchange resin material in deoxygenated water positioned in a liquid impermeable compartment of a gas impermeable vessel is also provided. A vessel containing deoxygenated water and virgin ion exchange resin material and an oxygen scavenging material is also provided.

First claim

What is claimed is:

1. A method of stabilizing virgin ion exchange resin material, the method comprising:
rinsing the virgin ion exchange resin material with deoxygenated water to produce a rinsed virgin ion exchange resin material;
introducing the rinsed virgin ion exchange resin material into a liquid impermeable compartment of a gas impermeable vessel; and
hermetically sealing the vessel.

2. The method of claim 1 , further comprising introducing an oxygen scavenging material into the gas impermeable vessel.

3. The method of claim 2 , comprising positioning the oxygen scavenging material between an exterior wall of the liquid impermeable compartment and an interior wall of the gas impermeable vessel.

4. The method of claim 1 , comprising introducing the rinsed virgin ion exchange resin material into the gas impermeable vessel comprising at least one of polyethylene terephthalate, stainless steel, and epoxy-lined carbon steel.

5. The method of claim 1 , comprising rinsing the virgin ion exchange resin material with deoxygenated water having a concentration of dissolved oxygen of less than about 10 ppb.

6. The method of claim 5 , comprising rinsing the virgin ion exchange resin material in the gas impermeable vessel.

7. A method of stabilizing virgin ion exchange resin material, the method comprising:
rinsing the virgin ion exchange resin material with deoxygenated water to produce a rinsed virgin ion exchange resin material;
introducing the rinsed virgin ion exchange resin material into a gas impermeable vessel;
introducing an oxygen scavenging material into the gas impermeable vessel, the oxygen scavenging material being positioned such that it does not come into direct contact with moisture; and
hermetically sealing the vessel.

8. The method of claim 7 , further comprising introducing the rinsed virgin ion exchange resin material into a liquid impermeable compartment of the gas impermeable vessel.

9. The method of claim 8 , comprising positioning the oxygen scavenging material between an exterior wall of the liquid impermeable compartment and an interior wall of the gas impermeable vessel.

10. The method of claim 7 , wherein introducing the oxygen scavenging material comprises introducing a material comprising a ferrous compound, catechol, ascorbate, ascorbic acid, sodium hydrogen carbonate, citrus extract, an oxidative enzyme, an unsaturated hydrocarbon, a polyamide, or combinations thereof.

11. The method of claim 7 , further comprising introducing an indicator of oxygen contamination.

12. The method of claim 11 , wherein introducing the indicator of oxygen contamination comprises introducing a visual indicator having a redox midpoint potential E 0 between about −0.05 V and about +0.06 V at pH 7 and 25° C.
