Abstract
Provided are sequestering agents for sequestering non-water moieties from an aqueous solution. The sequestering agents may comprise a detergent; and a polymer operable to stabilize formation of a detergent micelle thereby causing the detergent and polymer to self-assemble into a nanonet upon exposure to the aqueous solution. Also provided are kits therefore and methods for use of the sequestering agents and kits.
Claims23
A sequestering agent for sequestering non-water moieties from an aqueous solution comprising:
- a) a detergent able to form a micelle having a size of not less than about 10 kDa, wherein the detergent is selected from the group consisting of:
- 2-[4-(2,4,4-trimethylpentan-2-yl)phenoxy]ethanol (C14H22O(C2H4O)n (n=9-10)), 2-[4(2,4,4-trimethylpentan-2-yl)phenoxy]ethanol (C14H22O(C2H4O)n (n=30)), N-dodecyl-beta-D-maltoside (DDM), sodium oleate, and mixtures thereof;
- and
- b) a polymer having a molecular weight in a range of from about 3,000 g/mol to about 25,000 g/mol selected from the group consisting of styrene-maleic acid (SMA), Di-isobutyl maleic acid, and mixtures thereof.

A kit for sequestering non-water moieties from an aqueous solution, the kit comprising:
- a) a detergent able to form a micelle having a size of not less than about 10 kDa, wherein the detergent is selected from the group consisting of:

- b) a polymer having a molecular weight in a range of from about 3,000 g/mol to about 25,000 g/mol selected from the group consisting of styrene-maleic acid (SMA), Di-isobutyl maleic acid, and mixtures thereof;
- and
- c) a precipitation agent selected from the group consisting of:
- acetic acid, malic acid, citric acid, tartaric acid, fumaric acid, lactic acid, hydrochloric acid, sulfuric acid, phosphoric acid, and mixtures thereof.
