    exchange is not effective to remove As IIIi (arsenite, as H 3 AsO 3 or HAsO2), since they are not charged (ionized), so it is necessary to oxidize it to As V by an acceptable technique (chlorination, permanganate or ozonation). Optimum pH for anion exchange removal is approximately 7. Regeneration can be done with brine (NaCl) solution.

Arsenic is highly toxic and has been classified by the US EPA as a carcinogen, which was derived from toxicity considerations rather than carcinogenicity.

  • Arsenic Removal Technologies

    May 21, 2019Most 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.

  • Adsorption Media

    Many of these media can achieve high arsenic removal in the presence of interfering substances and in higher pH conditions. The capacity for arsenic removal by AA is pH dependent. If the pH range deviates from the range pH 5.0 - 6.0, the adsorption capacity for arsenic decreases at an increasing rate.
