Described herein is a method of removing mercury from an aqueous solution comprising: providing an aqueous solution comprising chloramine and mercury; and contacting the aqueous solution with a medium comprising a porous carbon substrate comprising at least 1.5% by mass of sulfur.

Removal of chloramine and mercury from aqueous solutions

Described herein is a filtration medium comprising a substrate, wherein the substrate comprises a thermolysis product of (i) a carbon substrate having a surface of COE, wherein E is selected from at least one of S, Se, and Te; and wherein x and y are greater than 0; and (ii) a metal salt; and methods of removing chloramine from aqueous solutions.

Filtration medium comprising a thermolysis product of a carbon oxychalcogenide and a metal salt, method of removing chloramine with this filtration medium and method of making this filtration medium

Described herein is a liquid filtration device is disclosed comprising a fluid conduit fluidly connecting a fluid inlet to a fluid outlet; and a water filtration medium disposed in the fluid conduit; the water filter medium comprising a metal-containing particulate, wherein the metal-containing particulate comprises a thermolysis product of a metal carboxylate; and methods of removing chloramines from aqueous solutions.

Filtration medium comprising a metal-containing particulate

Described herein is a liquid filtration device is disclosed a vessel for treating an aqueous liquid, wherein the vessel contains a filtration medium and wherein the filtration medium comprises a metal sulfide, wherein the sulfur in the form of a metal sulfide is at least 0.5% by weight of the filtration media.

Filtration medium comprising a metal sulfide

Described herein is a liquid filtration device is disclosed comprising a fluid conduit fluidly connecting a fluid inlet to a fluid outlet; and a water filtration medium disposed in the fluid conduit; the water filter medium comprising a metal-containing particulate, wherein the metal-containing particulate comprises a thermolysis product of a metal salt wherein the salt is selected from nitrogen-containing oxyanions, sulfur-containing anions, chlorides, phosphates, and combinations thereof; and methods of removing chloramines from aqueous solutions.
