Phosphorus capture from subsurface drainage water using iron-activated alumina (Alcan): Column adsorption, regeneration, and agronomic reuse evaluation

Key Points

• Phosphorus capture from drainage water showed significant potential for agronomic reuse.
• Adsorption efficiency reached up to 90% under optimal conditions, with a high regeneration potential.
• Column adsorption experiments were conducted to evaluate the effectiveness of iron-activated alumina for phosphorus removal.
• This method highlights sustainable approaches to manage nutrient runoff from agricultural lands.
