Abstract
The present disclosure provides compounds of Formula (I), their methods of preparation, their methods of regeneration of the compound of Formula (I), and their methods of use for binding perfluoroalkyl substances (PFAS) contaminates from sources of PFAS contaminated water.
Claims20
A compound of Formula (I) or a salt thereof:
- wherein W is selected from the group consisting of CH2, CH2CH2 and CH2CH2CH2;
- X is imidazolium;
- Y is selected from the group consisting of CH2CH2, CH2CH2CH2, and CH2CH2CH2CH2;
- and
- Z is selected from the group consisting of C6F13, C8F17, and C10F21.
2 more elements
A method of removing a PFAS contaminate from PFAS contaminated water supply comprising:
- a) contacting the PFAS contaminated water supply with a compound of Formula (I);
- b) binding a PFAS contaminate in the PFAS contaminated water supply with the compound of Formula (I) forming a PFAS bound compound of Formula (I);
- and
- c) isolating the PFAS bound compound of Formula (I) from the PFAS contaminated water supply.
1 more element
A method for regenerating a compound of Formula (I) from a PFAS bound compound of Formula (I) comprising:
- a) washing the PFAS bound compound of Formula (I) with different concentrations of an aqueous solvent, an organic solvent, different mixtures of an organic/different concentrations of an aqueous solvent mixture, or a combination thereof forming the compound of Formula (I);
- b) washing the compound of Formula (I) from step (a) with water;
- and
- c) drying the compound of Formula (I) from step b).
