I rece'd notice today my email server is being flipped to another company, and I'm madly opening stale Q&A from my old chem mentor, saving and indexing. And I AM confused. One reply from him says, "no, Activated Charcoal cannot remove chlorine because A.C. doesn't remove cations." Then in same reply he says this: #4. Chlorine in water is an anion not a cation. You can have chlorine compounds, such as chlorides, chlorates, that are not anions, but nascent chlorine is anionic.
He is literally dying of heart failure and only a few weeks to live. His hearing has gone to hell and he's given up his computer email usage. I'm interested in some direct response as I was a do this/do that lab assistant without a chemistry background. A gopher/doo-fer basically. I would most appreciate any clarity. Thank you for any assistance.
