Dual impregnated activated carbon

摘要

A dual-impregnated activated carbon composition includes activated carbon impregnated with a Group 6-12 metal salt and a Group 1 metal carbonate salt, where the molar ratio on the activated carbon of the Group 1 metal to the Group 6-12 metal is 1 or greater. The dual-impregnated activated carbon composition is particularly suitable for filtering gaseous contaminants.
