Adsorbent Performance of Solid Porous Carbon Derived from Waste Cigarette Filters

Introduction: Solid porous carbon (SPC) with micro-mesopore structures was successfully fabricated from used cigarette filters via carbonization. Experimental: The morphology and structure of the as-prepared porous carbon materials were characterized using X-ray diffraction, Fourier-transform infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. Results: This novel carbon material allows the removal of organic pollutants from water. The maximum adsorbed capacity of methylene blue could reach ~185 mg.g-1, which was attributed to the high specific surface area (567.7 m2.g-1) and the micro-mesoporous structure of the samples. Conclusion: Furthermore, when genomic stability was maintained in the solution, SPC was easily extracted. The mechanism for the fabrication of the proposed used cigarette filter is elucidated in this study.
