Abstract
Solid-supported trithiol compounds are prepared. The solid-supported trithiol compounds have formula (I): in which R is a linker moiety, X is a solid support, and n≧1. The compounds of formula (I) may be incorporated into methods for removing heavy metals from solutions and into batch systems or filtration apparatus that remove heavy metals from solutions.
Claims20
A solid-supported trithiol compound having formula (I):
- where X is a solid support, R is a linker moiety, and n≧1.
A method for removing heavy metals from a solution containing the heavy metals, the method comprising:
- contacting the solution with a solid-supported trithiol compound having formula (I):
- in which X is a solid support, R is a linker moiety, and n≧1;
- and
- forming complexes of the heavy metals with the compound of formula (I) to remove the heavy metals from the solution.
A heavy-metal removal system that removes heavy metals from a solution containing the heavy metals, the removal system comprising:
- a containment vessel having a vessel inlet and a vessel outlet in fluidic communication with the vessel inlet;
- at least one solid-supported trithiol compound having formula (I):
- in which X is a solid support, R is a linker moiety, and n≧1,
- wherein the filtration system is configured such that the solution enters the containment vessel through the vessel inlet and contacts the at least one solid-supported trithiol compound exiting the containment vessel through the vessel outlet.
