Abstract
Official abstract text for this publication.
Described herein is a filtration medium comprising a carbon substrate having a surface of CO x E y , wherein E is selected from at least one of S, Se, and Te; and wherein x is no more than 0.1 and y is 0.005 to 0.3; a filtration device comprising the filtration medium; and methods of removing chloramines from aqueous solutions.
First claim
Opening claim text (preview).
What is claimed is: 1. A filtration device comprising a carbon block, the carbon block comprising (i) a plurality of first activated carbon particles, wherein the first activated carbon particles have a surface of CO x S y ; and wherein x is no more than 0.1, and y is 0.005 to 0.3; and (ii) a binder comprising polyethylene. 2. The filtration device of claim 1 , wherein the carbon block further comprises an adsorbent. 3. The filtration device of claim 1 , wherein the polyethylene is an ultra high molecular weight polyetheylene. 4. The filtration device of claim 1 , wherein the first activated carbon particles have an average diameter of at least 5 micrometers and at most 500 micrometers. 5. The filtration device of claim 1 , wherein the activated carbon particle of the first activated carbon particles is derived from coconut shells. 6. The filtration device of claim 1 , wherein the plurality of first activated carbon particles comprises greater than 6.0 mass % sulfur based on the total mass of the first activated carbon particles. 7. The filtration device of claim 1 , wherein the carbon block further comprising a plurality of second activated carbon particles. 8. The filtration device of claim 7 , wherein the plurality of second activated carbon particles comprises less than 1 mass % sulfur based on the total mass of the second activated carbon particles. 9. The filtration device of claim 1 , wherein the carbon block is disposed in a housing.
