That is a very interesting article. It also discusses the use of
activated carbon to remove free chlorine and chlormaine.

Chloramines + activated carbon end up with chloride ion, hydrogen ion
plus nitrogen gas.

It seems that when hypochlorous ions (bleach) contact carbon, the net
effect is to create hydrogen ions and chloride ions.. I had always
thought that the chlorine was adsorbed to the carbon and just
sequestered out of the water. instead, it is reacted to chloride
ions. I feel a lot more comfortable with carbon now knowing that the
cartridge is not just filling up with toxic chlorine waiting to
release into my aquarium.
