Abstract
In this study, Fe-based Metal Organic Frameworks (MOFs) will be developed as a binding agent in Diffusive Gradient in Thin Film (DGT) for phosphate adsorption, where it will be evaluated for the effect of pH, adsorbent concentration and mixing time in phosphate loading capacity of Fe-based MOFs in DGT because these parameters can influence the capacity of phosphate adsorption. Fe-based MOFs were synthesized using ferrichloride as a binding agent and terephthalic acid as a linker in solvothermal conditions. Fe-based MOFs will be characterized by X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX), Brunauer-Emmelt Tellers (BET). The XRD peaks correspond to MIL-101 for 2 θ around 9 ° and 17 °. FTIR analysis indicated the broadening peak at 1595 cm−1 for C=O and 1395 cm−1 for C-C vibrational. The SEM analysis showed the morphology was rhombus. The BET analysis showed the surface area of Fe-based MOFs was 61.33 m2g−1. Fe-based MOFs have been successfully synthesized by the solvothermal method and then will be applied as binding agent in DGT. Furthermore, Fe-based MOFs in DGT will be used for phosphate adsorption and measured using Spectrophotometer UV-Vis.
