Abstract:
Background/Need: Arsenic is a well known pollutant and of high concern in many areas of Wisconsin. The EPA limit for arsenic in drinking water is 10ug/L or 10ppb; while instruments such as ICP-MS or GFAAS are able to accurately detect arsenic concentrations in this range they are impractical for field measurements. Thus, a need exists for a technology/technique that can accurately detect low concentrations of arsenic in the field.
Objectives: To develop a field-deployable arsenic sensor utilizing electrochemical impedance spectroscopy (EIS) and metal oxide thin-film coatings.
