Effect of Mn/Zn/Fe Oxy(Hydroxide) Nanoparticles Doping onto Mg-Al-LDH on the Phosphate Removal Capacity from Simulated Wastewater.

A parent Mg-Al-LDH was upgraded in its adsorption properties due to the incorporation of tri-metal species oxy(hydroxide) nanoparticles obtaining Mn/Zn/Fe/Mg-Al-LDH composite for the phosphate recovery from simulated urban treated wastewater. The physicochemical properties of the synthesized Mn/Zn/Fe/Mg-Al-LDH make promising for real application without being environmentally harmful. The performance of Mn/Zn/Fe/Mg-Al-LDH composite was evaluated through batch adsorption assays.

LTA and FAU-X Iron-Enriched Zeolites: Use for Phosphate Removal from Aqueous Medium.

Hydrothermally synthesized Linde type A (LTA) and faujasite X (FAU-X) zeolites are low-cost and environmentally benign inorganic carriers for environmental applications. In this study, (oxy)hydroxides were incorporated onto LTA and FAU-X zeolites to promote the phosphate adsorption. The performance of LTA-Fe and FAU-X-Fe was evaluated through batch adsorption assays.
