The perchlorate anion (ClO 4 m ) is produced when the solid salts of ammonium, potassium, and sodium perchlorate, and perchloric acid dissolve in water. Ammonium perchlorate, used in solid rocket engine fuels, has a limited shelf life and must periodically be replaced. Before 1997, perchlorate could not be readily detected in groundwater at concentrations below 100 µg/L, until the California Department of Health Services developed an acceptable analytical method that lowered the detection limit… Expand
Bioelectrical Perchlorate Reduction and Characterization of Novel Dissimilatory Perchlorate Reducing Bacteria
Perchlorate (ClO4-) is a soluble anion that occurs naturally in small concentrations, however, as a widely used oxidant in solid munitions, it has become a significant contaminant in ground waterExpand
Perchlorate as an emerging contaminant in soil, water and food.
TLDR
Perchlorate can be effectively removed by wide variety of remediation techniques such as bio-reduction, chemical reduction, adsorption, membrane filtration, ion exchange and electro-red reduction. Expand
