Fabrication of lanthanum linked trimesic acid as porous metal organic frameworks for effective nitrate and phosphate adsorption

The potable water crisis worldwide may lead to the detoxification of aquatic pollutants which becomes the research hotspot. The construction of metal-organic frameworks (MOFs) serves as the promising adsorbent material for the efficient removal of toxic ions from aqueous solution. Hence, the present research article covers the development of lanthanum linked trimesic acid (LTA) based MOFs for soluble nitrate (NO3-) and phosphate (PO43-) adsorption from water. The developed LTA MOFs were characterized by numerous instrumentation techniques like FTIR, SEM, EDAX, XRD, TGA, DTA and BET studies. The function of LTA MOFs declares the enhanced removal properties on NO3-/PO43- adsorption at batch condition. The adsorption mechanism of LTA MOFs was explored along with kinetics, isotherms and thermodynamic studies. The emerging trends of LTA MOFs for controlling the water quality parameters were also discussed at field level. The synthesized LTA MOFs could be reused many cycles for adsorption technique.
