Influence of pH and sulfate concentration on hydrous ferric arsenate transformation behavior and As(v) mobilization

Key Points

• Sulfate significantly influences hydrous ferric arsenate precipitation and arsenic mobility.
• Changes in pH alter the behavior of hydrous ferric arsenate, impacting arsenic release.
• The precipitation behavior of hydrous ferric arsenate is crucial for understanding arsenic mobilization.
• Arsenic mobilization is affected by both sulfate concentration and pH levels in the environment.
