Abstract
Provided is a method of extracting a metal ion, which comprises contacting a compound of formula (R2SiO)n with a source of the metal ion, whereby the compound and the metal ion form a complex, wherein each R is independently C1-10alkyl, and n is 3-10.
Claims19
A method of extracting a metal ion from a source, the method comprising:
- contacting a compound of formula (R2SiO)n with the metal ion in the source, whereby the compound and the metal ion form a complex;
- wherein each R is independently selected from C1-10alkyl, and n is 4,
- wherein the metal ion is a lithium ion, and
- wherein the concentration of the metal ion in the source is about 1×10−6 M to about 1×10−1 M.
1 more element
A method of extracting lithium ion from a source, the method comprising:
- contacting octamethylcyclotetrasiloxane with the lithium ion in the source, whereby the octamethylcyclotetrasiloxane and the lithium ion form a complex,
