In the present study, Zirconium Fumarate (Zr-fum) metal-organic framework (MOF), solvothermally synthesized at 130oC and characterized by using powder X-ray diffraction analysis (PXRD), porosity measurements using N2 sorption isotherms at 77 K and FTIR spectroscopy. The phosphate removal efficiency (% removal) obtained by 0.05 g/L adsorbent dose at an initial phosphate concentration 60 ppm in 3 hours was 72.47% whereas 100 and 89.88 % of phosphate removal efficiency was obtained at an initial phosphate concentrations of 5 and 20 ppm, respectively within 30 min for the same adsorbent dose. The BET surface area and pore volume of the bare Zr-fum sample was 478.25 m2/g and 0.52 cm3/g, respectively whereas after phosphate adsorption (at an initial concentration 60 ppm, 3 hours) the BET surface area and pore volume were reduced to 331.66 m2/g and 0.39 cm3/g, respectively. |
