[Problem] To provide: a nanocomposite capable of easily and efficiently removing and simultaneously absorbing an oily component, a heavy metal, hydrogen sulfide, and an organic compound merely by adding wastewater, without requiring a pretreatment such as oil removal, desalinization, or hydrodesulfurization, capable of easily recovering the same after absorption, and further capable of being used in the purification of wastewater in a broad pH range from acidic to slightly alkaline; a method for producing the same; an absorbent containing the nanocomposite; and a method for using the same. [Solution] A nanocomposite according to the present invention is characterized in that magnetite nanoparticles are conjugated with an organic nano-material represented by general formula (1). In general formula (1), R represents a C6-24 hydrocarbon group, R' represents an amino acid sidechain, and m represents an integer of 1-5. |
