| 英文摘要 | Bismuth impregnated biochar were synthesized to deal with wastewater pollution. nitrogen adsorption-desorption isotherms, scanning electron microscopy (sem), fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) and x-ray photoelectron spectroscopy (xps) were used to determine the characteristics of adsorbents and explore the main adsorption mechanism. results showed that bismuth particle was carried successfully within the biochar matrix, making contributions to creating micropore and boost specific surface area. the loaded bismuth, served as the adsorption site, rather than the specific surface area played an important role in arsenic and phosphorus adsorption. batch adsorption experiments demonstrated a fit langmuir model for arsenic (as) and phosphorus (p) and a suitable freundlich model for chromium (cr). thermodynamic parameters depicted the endothermic nature and the spontaneous process for phosphate and arsenic adsorption. besides, this contaminant-loaded carbon adsorbent was further applied for the removal of methylene blue from aqueous solution.
