Detailed Characterization of Arsenic Adsorptive Media
EMSL Project ID
26705
Abstract
Adsorptive media are being evaluated and demonstrated by the U.S.EPA for their effectiveness for arsenic removal from small drinking water supplies. Data collected from an EPA-funded, multi-column pilot-plant study indicate the presence of a significant amount of As(III) in the effluent of the adsorption columns, which were loaded with various adsorptive media for As(V) removal. It is important to know if the adsorption process, in fact, induces the formation of As(III), and if so, under what conditions As(III) would form, and what we can do to prevent or cope with its formation in the treated water. (Note that As(III) is the more toxic form of arsenic.) This information will be useful to the U.S.EPA, State drinking water officials, and water utility operators when using adsorption systems for arsenic removal.
