Abstract:
Arsenic in drinking water is a worldwide concern. In nature, arsenic appears in ground water mainly as arsenite [As (III)] and arsenate [As(V)]. An acceptable norm in many countries, including India, for arsenic (expressed as total arsenic) in drinking water is 10 µg/L . One significant problem encountered in the removal of arsenic from groundwater aquifers and municipal water systems is that arsenic exists as both arsenic (III) compounds and arsenic (V) compounds in water. Arsenic (III) compounds are primarily non-ionic whereas arsenic (V) compounds are primarily ionic at normal drinking water pH levels (ref. 6). Arsenic (III) compounds, or arsenites, are therefore not always readily removed from drinking water by methods that are very effective for removal of arsenic (V) compounds or arsenates. It is sometimes necessary to pre-oxidize any arsenates present to arsenates in order to effectively remove arsenic from drinking water to safe levels. An oxidant that itself or its’ products of oxidation are not toxic must introduced into the drinking water to accomplish this.
