post synthetic modified mof for nitrate removal from aqueous solution by mof

Metal-organic frameworks have been used because of their unique properties for various applications including adsorption. these compounds are a good base for loading different species because of their modifiable structure. in this project, modified metal-organic framework was used as adsorbent in adsorption of nitrate from aqueous solution. the hkust framework was first synthesized and modified by the 4-aminopyridine functional group (hkust-amp), the sorbent used to remove nitrate from aqueous solution. the product characterized by infrared spectroscopy, powder x-ray diffraction, elemental analysis and scanning electron microscopy, thermal gravimetry and absorption- desorption nitrogen gas. nitrate adsorption process from aqueous solution was investigated at 25°c, 30 min, ph=5 by uv-visible spectroscopy. nitrate removal from aqueous solution by adsorbent 70% was calculated.
