Abstract
This research contains data on the adsorption test and characterization of banana peel activated carbon as an adsorbent for water contaminated with various heavy metals. Banana peel is a common post-harvest waste, making it easy to obtain. Atomic Absorption Spectroscopy (AAS) is used to investigate the various heavy metal content in polluted water that are harmful to health, such as Mn, Fe, Zn, and Pb in concentrations of 1.351; 1.210; 17.403; and 0.210 mg/L, respectively. These metals exceed the standard limits for clean water quality that are suitable for sanitation hygiene purposes. Banana peel activated carbon samples were tested in polluted water and re-examined using AAS. The parameters used to calculate the percent adsorption of the four heavy metals were variations in adsorbent mass (0.5; 1.0; 1.5; 2.0 g), stirring speed (50; 100; 150; 200; 250 rpm), pH (4; 5; 6; 7; 8; and contact time (30; 60; 90; 120; 150 min). Scanning Electron Microscopy/X-Ray Spectroscopy Energy Dispersion (SEM/EDS) and X-Ray Diffraction (XRD) were used to characterize and determine the morphology, material content, and crystal structure formed by the samples. Brunaurer, Emmet, and Teller/Barret, Joyner, and Halenda (BET/BJH) were used to investigate the surface area, pore size, and isotherm type. This dataset is publicly available for researchers to optimize the potential of banana peel activated carbon as an adsorbent of heavy metals (Mn, Pb, Zn, Fe) in the industrial sector.
