▎ 摘　　要

NOVELTY - Nanofilter comprises one or more hydrophobic nanoparticles, an amorphous carbon, and a support comprising a polymeric sponge or a fabric, where the hydrophobic nanoparticles and the amorphous carbon are impregnated on the support to provide the nanofilter. USE - The nanofilter is used for selectively separating oil contaminants from water (claimed). The nanofilter is used in environmental remediation to eliminate various contaminants from water. The oil contaminants include crude oil, diesel, engine oil, and petrol oil. ADVANTAGE - The nanofilter provides high removal capacity of oil in water, and is reusable in multiple separation cycles, stable at various pH and temperature conditions and suitable for large scales at low cost. The nanofilter absorbs wide range of oils with good recyclability and has extended surface area for better removal capacity. The adsorption of the oil contaminants on the nanofilter substantially retains total solids dissolved in water. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: use of the nanofilter for selectively separating oil contaminants from water; a method for producing the nanofilter for oil-water separation; and a method for selective separation of oil contaminants from water.
