“Tortoise and Hare” strategy: Polyethyleneimine/sodium alginate-functionalized iron tailings regulate Pb Cu diffusion priorities for remediating contaminated soil

Key Points

• Lead and copper diffusion priorities were effectively regulated, improving remediation outcomes.
• The intervention demonstrated a specific focus on heavy metal control using functionalized materials.
• Assessment using observational analysis of polyethyleneimine and sodium alginate-functionalized iron tailings.
• Highlights the potential of this strategy for soil remediation, suggesting broader applications in environmental cleanup.
