Both disinfect by oxidizing the cell membrane of microorganism, a process by which their molecules receive electrons from those membranes. A chlorine molecule can receive two electrons, while chlorine dioxide can receive five, which makes it that much more effective. And we can see that in action when we purify water.

Both disinfectants are capable of killing bacteria and viruses, but chlorine has limited effectiveness on cysts and protozoa, and may not be strong enough to kill stuff like Giardia or Cryptosporidium, while chlorine dioxide can. For that reason, the Centers for Disease Control recommends that you combine chlorine with filtration to clean water before drinking it.
