| Abstract: | "Four novel fruit-derived biochars were developed: pomegranate peels (PB), prickly pear peels (PPB), carob (CB), and locust bean gum (LBGB). The feedstocks were pyrolyzed at 350 and 550 ?SG (under N(2)), respectively, and characterized using Scanning Electron Microscopy (SEM), Elemental Analysis (EA), Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS), Brunauer-Emmett-Teller (B.E.T) analysis, and Thermogravimetric analysis (TGA). A systematic and comprehensive comparison for the adsorption of selected volatile organic compounds (VOCs) by biochar was established. Cresol, dimethyl trisulfide (DMTS), hexane, and benzene were examined as a function of contact time (30-480 min), mass (0.1-1 g), concentration levels (50-1000 ppb(v)), efficiency, and reusability, using the headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) method. PB 550 ?SG revealed a specific surface area of 8.3 m(2) g(-1), the fastest complete removal, an ideal mass of 1 g, 3-times reuse, and approximately 99% removal of 500 ppb(v) benzene, cresol, DMTS, and 100 ppb(v) hexane" |
