Abstract
Materials and methods for extracting metals from solutions, involving a polymer of Formula A are described: where each X is independently either S or O, and n is an integer greater than 1.
Claims17
A composition comprising Formula A:
- wherein:
- each X is independently either S or O, provided that at least one X is O, and
- n is an integer greater than 1;
- and salts, stereoisomers, racemates, hydrates, solvates, polymorphs, and complexes thereof.

A composition comprising Formula IV:
- wherein n is an integer greater than 1.
A composition comprising Formula A dispersed in a solution:
- wherein:
- each X is independently either S or O, and
- n is an integer greater than 1;
- or a salt, stereoisomer, racemate, hydrate, solvate, polymorph, or complex thereof;
- wherein Formula A is uniformly dispersed in the solution.
