Q » Why is granular ferric hydroxide (GFH) used for arsenic removal?
03 Nov, 2025
A » Granular ferric hydroxide (GFH) is used for arsenic removal due to its high adsorption capacity, efficiency in targeting both arsenic(III) and arsenic(V), and stability under various water conditions. Its porous structure increases the surface area for interaction, making it effective in reducing arsenic levels to meet safety standards. Additionally, GFH is easy to handle, regenerable, and environmentally friendly, enhancing its suitability for water purification applications.
