Key Points

Chemical reduction significantly lowers Cr(VI) levels in groundwater, improving safety and health.
The FeS2/red soil-analcime zeolite composites achieved over 90% removal of Cr(VI) in controlled tests.
The study employs a combined approach using chemical reduction and ion-exchange processes.
These findings highlight a potential environmentally friendly solution for chromium contamination.

Implication

Chemical reduction and ion-exchange effectively stabilize chromium in groundwater, suggesting a new mitigation method.

Abstract

Reduction and stabilization of hexavalent chromium (Cr(VI)) in groundwater are essential for mitigating environmental and human health risks. In this work, we demonstrate the development of FeS2/Re-ANA composites (PM/RAs), a...
