Converting waste into a resource: ethylenediamine modification of iron blast furnace slag to fabricate a cost-effective adsorbent for effective Pb( ii ) removal

Key Points

• The aim is to develop a cost-effective adsorbent using iron blast furnace slag for lead removal from wastewater.
• Modified iron blast furnace slag using ethylenediamine.
• Investigated the adsorbent's effectiveness in removing Pb(II) from solutions.
• The new adsorbent showed a significant capacity for lead removal.
• Demonstrated improvement in cost-effectiveness compared to traditional methods.
