Iron oxide xerogels for improved water quality monitoring of arsenic( iii ) in resource-limited environments via solid-phase extraction, preservation, storage, transportation, and analysis of trace contaminants (SEPSTAT)

We show that iron oxide xerogels can quantitatively adsorb, store, and release aqueous arsenic(iii), enabling a new arsenic monitoring paradigm where sample contamination is adsorbed onto solid sorbents for transportation to laboratories for analysis.
