Nanostructured Mn-Fe Binary Mixed Oxide: Synthesis, Characterization and Evaluation for Arsenic Removal

Area of Science:

• Environmental Science
• Materials Science
• Chemistry

Background:

• Arsenic contamination in water poses significant health risks.
• Developing efficient adsorbents for arsenic removal is crucial for water purification.

Purpose of the Study:

• To synthesize and characterize a bimetallic manganese-iron mixed oxide (MFBMO).
• To evaluate the adsorption capacity of MFBMO for arsenic removal from water.

Main Methods:

• Hydrothermal synthesis of MFBMO.
• Characterization using X-ray diffraction (XRD) and scanning electron microscopy (SEM).
• Batch adsorption studies with Langmuir and Freundlich isotherm models.

Main Results:

• MFBMO was successfully synthesized and characterized.
• Adsorption capacity of 2.048 mg/g (Freundlich model) for simulated water.
• Adsorption capacity of 1.084 mg/g (Freundlich model) for field water.

Conclusions:

• Mn-Fe binary mixed oxide is an effective adsorbent for arsenic removal.
• The material shows promise for practical water treatment applications.
