You may still think it’s important to remove even trace amounts of this metal, though, especially because of the cancer risk. If so, I cover the best methods of arsenic removal at the bottom of this guide.
Arsenic Removal Technologies | SSWM - Find tools for,
Most arsenic removal technologies are most effective in removing the pentavalent form of arsenic (As(V), arsenate), since the trivalent form (As(III), arsenite) is predominantly non-charged below pH 9.2. Thus arsenate is much less mobile than arsenite, as it tends to co-precipitate out with metallic cations or to adsorb onto solid surfaces.
