Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
What is claimed is: 1. A hermetically sealed vessel comprising virgin ion exchange resin material in deoxygenated water having less than about 10 ppb dissolved oxygen, and an oxygen scavenging material. 2. The vessel of claim 1 , wherein the virgin ion exchange resin material in the deoxygenated water is positioned in a liquid impermeable compartment of the hermetically sealed vessel. 3. The vessel of claim 2 , wherein the oxygen scavenging material is positioned between an exterior wall of the liquid impermeable compartment and an interior wall of the vessel. 4. The vessel of claim 1 , wherein the oxygen scavenging material comprises a ferrous compound, catechol, ascorbate, ascorbic acid, sodium hydrogen carbonate, citrus extract, an oxidative enzyme, an unsaturated hydrocarbon, a polyamide, or combinations thereof. 5. The vessel of claim 1 , being constructed from a material comprising at least one of polyethylene terephthalate, stainless steel, and epoxy-lined carbon steel. 6. The vessel of claim 1 , further comprising an indicator of oxygen contamination.
