Abstract

One of the most important sources for human's life is water. However, nowadays water cannot be used properly due to the large amount of heavy metal that contaminates the water such as cadmium (Cd). Therefore, Metal Organic Framework (MOF), one of the porous materials used in the application for water treatment due to its large pore and surface area. In this research, MOF were synthesized using lanthanum and yttrium metals with succinate acid ligand, N,N-dimethylformamide (DMF) and water solvent using solvothermal method. MOF were characterized using Fourier Transform Infra Red (FTIR), X-Ray Diffraction (XRD), Surface Area Analyzer (SAA) and Scanning Electron Microscope (SEM). Furthermore, MOF were used as adsorbent of cadmium(II) metal ion with various variation such as pH, contact time, adsorbent dose and cadmium concentration. The results showed the optimum condition for Lanthanum-succinate MOF (La-MOF) at pH 5 with adsorbent dose 10 mg, cadmium concentration 12 ppm and contact time 45 min and for Yttrium succinate (Y-succinate) MOF were shown the optimum condition for each variation at pH 7 with adsorbent dose 20 mg, cadmium concentration 10 ppm and contact time 15 minutes. The adsorption capacity produced by La-succinate MOF is greater than Y-succinate MOF as well as the results of adsorption isotherm by La-succinate MOF and Y-succinate MOF. La-succinate MOF have R2 of 0.9946 with the value of adsorption capacity Freundlich of 2.296 mg/g and Y-succinate MOF have R2 of 0.8812 with the value of adsorption capacity Freundlich of 1.543 mg/g.
