This study aims to determine the influence of concentration of potassium hydroxide (KOH) on the adsorption of Pb2+ and Cu2+ metal ions in industrial used water. The activated carbon was prepared from pineapple crown waste. Pineapple crown was pre-carbonized at 180oC for 1 hours. Chemical activation was done using KOH with variations in concentrations of 2, 3, and 4 M. The samples were irradiated by using a microwave at 630 Watt of output power for 15 minutes. KOH activation and microwave irradiation power were influenced to the physical properties of the samples. Activated carbons formed were characterized using scanning electron microscope and energy dispersive X-ray to know surface morphology and component of the samples. Functional groups and microstucture obtained using spectroscopy Fourier infrared and X-ray diffraction. Adsorption of activated carbon analyzed using atomic adsorption spectrometry. The results showed that highest adsorption were obtained from activated carbon that was activated by KOH 2 M. Adsorption efficiency for Pb2+ and Cu2+ metals were 81.15% and 49.71%, respectively. This is corresponding to the best stack height (Lc) value of activated carbon is 10.470 nm. The carbon chain structure shows the functional groups C-H, C≡C, O-H, C-OH, and CH2 at wavenumber 2889.49 cm-1, 2360.97 cm-1, 2339.97 cm-1, and 998.21 cm-1.
Keywords: Pineapple crown, potassium hydroxide, microwave irradiation, activated carbon, physical properties, atomic adsorption.
