Gypsum-assisted Arsenic Remediation Using Zero Valent Iron (ZVI) and Sulfate-Reducing Bacteria (SRB)

Key Points

• The aim is to evaluate the effectiveness of gypsum-assisted arsenic remediation using zero valent iron and sulfate-reducing bacteria.
• Utilized gypsum in combination with zero valent iron (ZVI) for arsenic remediation.
• Incorporated sulfate-reducing bacteria (SRB) to enhance the remediation process.
• Monitored arsenic levels before and after intervention.
• Significant reduction in arsenic concentrations observed after treatment.
• Combination of gypsum, ZVI, and SRB showed enhanced remediation efficiency.
• Treatment led to a more stable arsenic compound, reducing leaching potential.
