Biomass is an inexpensive adsorbent that has attracted considerable interest. The sol-gel process produced xerogel from palm kernel shell biochar (PKSB). This study aimed to synthesize and characterize palm kernel shell biochar xerogel (PKSBX) and compare it with commercial (AC). The synthesized xerogel, raw material, and AC were characterized using different characterization, including thermogravimetric analysis (TGA), X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Brunauer-Emmett-Teller (BET), and Scanning Electron Microscopy (SEM). The FTIR spectrum analysis showed a wide range of bonds and confirmed the presence of C=C alkenes, amines N-H, and aromatic C-H functional groups. TGA analysis of samples was conducted at 10℃/min. The thermal degradation of the sample undergoes several setups of loss mass. The degrades occurred between 50200℃ first setups, second between 200–700℃, and third setups between 950–1000℃. The surface morphological structure of each sample has been defined and compared using SEM data, which is further confirmed by XRD data. On the basis of on the characterization findings, it can be determined that the xerogel obtained from the synthesis process using PKSB as the raw material exhibits favorable characteristics for its potential usage as an adsorbent.
