Abstract
This invention relates to an aqueous composition comprising, (a) an ion-exchange resin (IXR) comprising microporous beads having a particle size ranging from about 200 um to about 1000 um; (b) a water soluble surfactant having a molecular weight ranging from about 7,500 to about 15,000 Da; and (c) a buffer component; wherein the pH of the aqueous composition ranges from about 5 to about 8, and a process for isolating chemical contaminants using the aqueous composition.
Claims12
A process of isolating chemical contaminants, said process comprising contacting an absorptive zone with a source comprising the chemical contaminants, wherein the absorptive zone comprises an aqueous composition comprising:
- (a) an ion-exchange resin (IXR) comprising microporous beads having a particle size in the range from about 100 μm to about 1000 μm;
- (b) a water-soluble surfactant having a molecular weight in the range from about 7,500 to about 15,000 Da;
- and
- (c) a buffer component;
- wherein the pH of the aqueous composition is in the range from about 5 to about 8.
