Abstract: Described herein is a filtration medium and method for treating a chloramine-containing liquid. The active chloramine removal material comprises carbon, nitrogen, and sulfur, and the sum of the sulfur and nitrogen in the active chloramine removal material is at least 4.0 mass %.

Abstract: Conductive articles include an electrically insulating substrate with conductive regions on the substrate, the conductive regions are conductive patterns of a transparent conductor and a resist matrix. The substrate also has non-conductive regions, and exposed conductive contacts, where the conductive contacts are in electrical contact with the conductive regions. The non-conductive regions are formed by selective chemical etching of the transparent conductor coating, where the selective etching does not remove the conductive patterns or conductive contact.

Abstract: 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.

Abstract: Described is a method of removing chlorine from an aqueous solution by: providing an aqueous solution having chloramine and/or chlorine; and contacting the aqueous solution with a medium having a porous carbon substrate having at least 1.5% by mass of sulfur.
