If chlorine is adsorbed, and a ferrous ion comes by, does it react with the ion to make a ferric something?
I think the iron is reacted with prior to it reaching the carbon filter and that the carbon filter is mostly just a particle sieve with perhaps some amount of attraction. I don't think that backwashing regenerates in the same sense as softener resin. It just washes away the collected particulate. Maybe @ditttohead could give us a Reader's Digest explanation?

Regular carbon (GAC) does have some limited catalytic action but is mainly used as an adsorbent, whereas catalytic carbon is specifically modified to increase catalytic action.

The attached links provide info mainly concerning Chloramine reduction but also somewhat explain catalytic action.

By that theory, sand, or a lighter version such as Filter-Ag, would work as well. I am sure that is not the case.

Carbon can filter iron but carbon is not needed in an iron filter. IMHO iron filtering is not the primary use for carbon. Removing chlorine and other organics is its primary purpose.
