REMOVAL OF Cd2+ IN WASTEWATER USING ZEOLITIC IMIDAZOLATE FRAMEWORK-8 (ZIF-8) AS SYNTHESIS ADSORBENT

Zeolitic Imidazole Framework-8 (ZIF-8) has been synthesized by dissolving Zn(NO3)2.4H2O and 2-MeIM into a methanol solvent solvothermal method. The ZIF-8 will be applied as cadmium (Cd) adsorbent in Polluted water. Several characterization methods were conducted, including XRD, FTIR, AAS. XRD analysis shows that the prominent characteristic peaks of at an angle 2θ = 7,25o; 10,26o; 12,57o; 16,22o; 17,86o. At same time, FTIR showed presence functional groups Zn-N, C-N, C=N, C=C, C-H on aromatic 2-Methyl Immidazole indication completely established. Based result, AAS method performed to analyze ability adsorb Cd water ions adsorption increased pH 6 8 while decreasing 7.
