Abstract

This disclosure provides a halogenated activated carbon composition comprising carbon, a halogenated compound and a salt. In some embodiments, the halogenated compound and the salt comprise a naturally occurring salt mixture, as may be obtained from ocean water, salt lake water, rock salt, salt brine wells, for example. In some embodiments, the naturally occurring salt mixture comprises Dead Sea salt.

Claims (24)

1. A halogenated activated carbon composition, the composition comprising, on a dry basis, at least 85 wt % carbon; a halogenated compound; and a copper halide or Dead Sea salt; wherein the halogenated compound or the Dead Sea salt are present in a total amount of about 0.1 wt % to about 15 wt %.

2. The halogenated activated carbon composition of claim 1 , wherein the composition comprises at least 90 wt % carbon.

3. The halogenated activated carbon composition of claim 2 , wherein the composition comprises at least 95 wt % carbon.

4. The halogenated activated carbon composition of claim 1 , wherein the carbon comprises biogenic carbon.

5. The halogenated activated carbon composition of claim 1 , wherein the carbon consists essentially of biogenic carbon.

6. The halogenated activated carbon composition of claim 1 , wherein the composition comprises the halogenated compound and a copper halide.

7. The halogenated activated carbon composition of claim 1 , wherein the composition comprises the halogenated compound and the Dead Sea salt.

8. The halogenated activated carbon composition of claim 1 , wherein the composition comprises the halogenated compound, the copper halide, and the Dead Sea salt.

9. The halogenated activated carbon composition of claim 1 , wherein the halogenated compound and the Dead Sea salt are present in a total amount of about 1 wt % to about 10 wt %.

10. The halogenated activated carbon composition of claim 1 , wherein the halogenated compound comprises at least one of magnesium chloride, potassium chloride, sodium chloride, or calcium chloride.

11. The halogenated activated carbon composition of claim 1 , wherein the halogenated compound comprises at least one anion, wherein the anion is selected from the group consisting of chloride, bromide, iodide, fluoride, sulfate, nitrate, and phosphate.

12. The halogenated activated carbon composition of claim 11 , wherein the halogenated compound comprises at least two anions, wherein the at least two anions are selected from the group consisting of chloride, bromide, iodide, fluoride, sulfate, nitrate, and phosphate.

13. The halogenated activated carbon composition of claim 1 , wherein the halogenated compound or the Dead Sea salt comprises about 0.1 wt % to about 5 wt % bromide ion.

14. The halogenated activated carbon composition of claim 13 , wherein the halogenated compound or the Dead Sea salt comprises about 0.2 wt % to about 2 wt % bromide ion.

15. A biogenic activated carbon composition comprising, on a dry basis:

at least about 80 wt % total carbon;

at most about 10 wt % hydrogen; and

a first salt, wherein the first salt comprises a halogenated compound, and wherein the halogenated compound is selected from the group consisting of copper bromide, copper chloride, and combinations thereof, and

a second salt;

wherein the halogenated compound and the second salt are present in a total amount of about 0.2 wt % to about 20 wt %, and wherein the second salt is optionally halogenated.

16. The biogenic activated carbon composition of claim 15 , wherein the first salt and the second salt are present in a total amount of about 1 wt % to about 15 wt %.

17. The biogenic activated carbon composition of claim 15 , wherein the halogenated compound comprises about 0.1 wt % to about 5 wt % bromide ion.

18. The biogenic activated carbon composition of claim 15 , comprising a naturally occurring salt mixture, and wherein the first salt or the second salt are comprised within the naturally occurring salt mixture.

19. The biogenic activated carbon composition of claim 18 , wherein the naturally occurring salt mixture is from a source selected from the group consisting of ocean water, salt lake water, rock salt, salt brine wells, and combinations thereof.
