Abstract: The present disclosure discloses a silicon-aluminum-iron composite material and a preparation method therefor and use thereof, and belongs to the technical field of wastewater treatment. The silicon-aluminum-iron composite material comprises an inner core and an outer shell wrapping the inner core; the inner core is a silicon-aluminum-based hollow sphere; the outer shell contains iron element; and there are holes on the silicon-aluminum-iron composite material. The silicon-aluminum-iron composite material of the present disclosure improves the specific surface area of the silicon-aluminum-iron composite material through structural adjustment. When it is used to adsorb heavy metal ions, the adsorption sites are correspondingly increased, which finally improves the adsorption capacity for heavy metal ions.

Abstract: Methods are provided for using a combination of nanomaterials and oil-degrading bacteria to detoxify a multiphasic liquid (e.g., an oil-water mixture) and to ameliorate the toxicity of oil to local organisms, e.g., meiobenthos, in or near the area of the multiphasic liquid. The methods can be utilized for oil recovery and environmental clean-up and detoxification after spills and discharges. Through synergistic combination of the nanomaterials with oil degrading bacteria, methods can ameliorate environmental damage due to the presence of oil in an area through increased activation of the bacteria as well as through removal of the oil.

Abstract: A preparation method and an application of a clay/tannic acid/metal ion composite material for efficient adsorption of antibiotics are provided, which relate to the field of water environment treatments. A clay/tannic acid/metal ion composite adsorbent is prepared, preparation method and operation process are simple, synthesis time is short, and yield is large. A raw material used is tannic acid, which has a wide range of sources, is non-toxic, biodegradable, and has no risk of secondary pollution, due to abundant phenolic hydroxyl groups in tannic acid, the tannic acid can not only chelate with the metal ions, but also adsorb pollutants from water, when combined with the clay and the metal ions, a composite body is formed, which has a rougher surface, and adsorption active sites are increased, thereby effectively increasing adsorption, and improving an adsorption performance for pollutants. The clay/tannic acid/metal ion composite adsorbent has good adsorption effect for antibiotics.

Abstract: Sorbents are disclosed which exhibit less inherent leaching of arsenic and antimony than what is achieved by conventional sorbents. The inventive sorbents are formed by a process which includes the steps of contacting the porous sorbent particulate with a solution of a metal oxide or metal hydroxide, or a metal oxide or metal hydroxide precursor, and depositing metal oxides and hydroxides within the pores of the porous sorbent particulate. Purification of water is also described.
