Arsenic contamination in drinking water poses a significant threat to global public health. Recognizing this urgent challenge, NINGBO INNO PHARMCHEM CO.,LTD. has been at the forefront of developing advanced materials for effective water purification. Our latest innovation, iron hydroxide nanopetalines, synthesized through a novel precipitation method using KBH4, represents a major leap forward in tackling arsenic pollution.

The research meticulously details the characteristics of these nanopetalines, revealing their superior performance in removing both pentavalent (As(V)) and trivalent (As(III)) arsenic compared to conventional ferrihydrite. The adsorption processes are remarkably rapid, achieving equilibrium within 24 hours, with initial stages showing significant uptake due to ample unoccupied adsorption sites. This efficiency is crucial for industrial applications where rapid water treatment is essential. Understanding the mechanism of arsenic removal by iron hydroxide is key to appreciating its effectiveness; it primarily involves surface hydroxyl exchange reactions with Fe–OH groups, forming stable inner-sphere surface complexes.

Our studies have quantified the exceptional adsorption capacity of iron hydroxide nanopetalines. At pH 4.0, the Langmuir model indicates capacities of 217.76 mg/g for As(V) and 91.74 mg/g for As(III). Even at pH 8.0, capacities remain high at 187.84 mg/g for As(V) and 147.06 mg/g for As(III). This broad applicability across different pH levels is a significant advantage. We also investigated the effect of pH on arsenic removal, finding that while As(V) removal is optimal at lower pH, As(III) removal shows a broader maximum between pH 6-9, showcasing the material's versatility.

Furthermore, the research addresses the real-world challenges of co-existing ions. The effect of competitive anions on arsenic removal, particularly phosphate and citrate, was analyzed. While sulfates show minimal interference, phosphate and citrate significantly reduce arsenic removal efficiency, highlighting the need for careful consideration of water matrix composition in practical applications. The reusability of iron hydroxide adsorbents was also thoroughly tested, with more than 67% of the removal efficiency for As(V) maintained after four cycles, underscoring its economic viability and sustainability.
