title: Removal of arsenic as arsenite from groundwater/wastewater as stable metal ferrite.
abstract: This paper summarizes the results of the study on removal of arsenite ions in liquid medium at an ambient temperature by ferritization and its application in wastewater/groundwater treatment. X-ray Diffractometry (XRD), thermal analysis and dc resistivity measurement have characterized the ferruginous material (Arsenic ferrite) precipitated by both the aeration and ageing procedures. The laboratory scale experiments conducted with synthetic solution of arsenite at different concentration suggest that the arsenite ions can be effectively retrieved > 99%. The recovered arsenic ferrites may find commercial application as semiconductors, catalysts, metal scavengers, etc.
