Method For Removing Chromium From Water Using Ion Exchange Resins Including Interpenetrating Polymer Networks

View page
US Patent:
8168070, May 1, 2012
Filed:
Dec 10, 2009
Appl. No.:
12/634709
Inventors:
Daryl J. Gisch - Midland MI, US
Jing Jin - Midland MI, US
Assignee:
Dow Global Technologies LLC - Midland MI
International Classification:
C02F 1/42
US Classification:
210684, 210688, 210913
Abstract:
The invention includes ion exchange resins and their use in the removal of chromium from water. In one embodiment, the invention comprises a method for removing chromium from a water source by contacting the water with an ion exchange resin, wherein the ion exchange resin comprises particles of a crosslinked copolymer comprising: an interpenetrating polymer network (IPN) of at least two polymer components each having a styrenic content greater than 50 molar percent, and a quaternary ammonium functionality.

US Patent:
8241505, Aug 14, 2012
Filed:
Feb 8, 2010
Appl. No.:
12/701644
Inventors:
Daryl J. Gisch - Midland MI, US
Assignee:
Dow Global Technologies LLC - Midland MI
International Classification:
C02F 1/42
US Classification:
210684, 210688, 210913
Abstract:
The invention includes ion exchange resins, methods of making ion exchange resins and their use in the removal of perchlorate from water. In one embodiment, the invention comprises a method for removing perchlorate from a water source by contacting the water with an ion exchange resin, wherein the ion exchange resin comprises particles of a crosslinked copolymer comprising: an interpenetrating polymer network (IPN) of at least two polymer components each having a styrenic content greater than 50 molar percent, and a quaternary ammonium functionality.

US Patent:
8273799, Sep 25, 2012
Filed:
Dec 10, 2009
Appl. No.:
12/634708
Inventors:
William I. Harris - Midland MI, US
Dennis A. Keeley - Beaverton MI, US
Daryl J. Gisch - Midland MI, US
Marvin H. Tegen - Midland MI, US
James A. Jagodzinski - Midland MI, US
David C. McDonald - Midland MI, US
Assignee:
Dow Global Technologies LLC - Midland MI
International Classification:
B01J 41/12
US Classification:
521 30, 521 27, 521 32
Abstract:
The invention generally relates to amination reactions and amination reaction products, and particularly to methods for aminating vinyl aromatic polymers utilizing tertiary amines. In one embodiment, the invention includes conducting an amination reaction by combining a tertiary amine and a vinyl aromatic polymer comprising benzyl chloride groups to form a reaction mixture and maintaining the pH of the reaction mixture within a designated range. In another embodiment, the invention includes an aminated vinyl aromatic polymer. In yet another embodiment, the invention includes an ion exchange resin including quaternary ammonium functionality. The invention is useful in preparing ion exchange resins suitable for a variety of applications such as the removal of perchlorate ions from water sources and recovery of gold cyanide from mining leach solutions.

US Patent:
52778134, Jan 11, 1994
Filed:
Dec 10, 1992
Appl. No.:
7/988610
Inventors:
Binyamin Feibush - State College PA
Daryl J. Gisch - Midland MI
Assignee:
S.A.C. Corporation - St. Louis MO
International Classification:
B01D 1508
US Classification:
2105021
Abstract:
Novel packing materials are provided for liquid chromatography and/or solid phase extraction columns which will allow direct injection of biological fluids. These packing materials have a hydrophilic exterior layer and a hydrophobic, charged or otherwise selective portion that forms an underlayer or is embedded in the hydrophilic layer. During a chromatographic process large water soluble biopolymers will be in contact with the hydrophilic outer layer and be shielded from interacting with the underlayer or embedded portion and elute unretained. Small analytes, on the other hand, can be fully partitioned throughout the exterior and interior layers and are retained by hydrophobic or electrostatic interactions. Using such packings the direct analyses of plasma or serum for drug analysis is demonstrated.
