Abstract

The quality of drinking water can be affected by many things, one of which is due to contamination of Lead (Pb) and Iron (Fe). An alternative that can be done to reduce the concentration of Pb2+ and Fe3+ metal ions in water is through an adsorption process using an adsorbent from Zeolitic Imidazolate Frameworks-8 (ZIF-8) material. ZIF-8 was synthesized by solvothermal method using methanol as solvent. ZIF-8 sample characterization was tested using XRD (X-Ray Diffraction) and FTIR (Fourier-Transform Infrared). The adsorption process of Pb2+ and Fe3+ metals in this study was carried out by varying the mass of the adsorbent and varying the contact time. Based on the influence of ZIF-8 mass, the highest adsorption capacity value was at 0.1 g ZIF-8 mass and the adsorption capacity decreased at 0.2 g ZIF-8 mass. Based on the effect of contact time, the highest adsorption capacity value was at 60 minutes contact time, the adsorption capacity value decreased when the contact time was increased to 90 minutes and decreased again at 120 minutes contact time. The synthesized ZIF-8 was effectively applied as an adsorbent for metals Pb2+ and Fe3+, this was indicated by the high adsorption proportion of ZIF-8
