Abstract

A nanocarbon immobilized membrane (NCIM) is disclosed. The nanocarbon immobilized membrane is sized to purify different organic-water mixtures. The nanocarbon immobilized membrane can be used to purify solvents, fuels, and other organic compounds. Data using heptane-water, octane-water, fuel-water, and paint thinner-water show 99.9% separation efficiency. High organic flux is also seen at relatively low pressure. This approach has numerous applications, including fuel purification, oil spills clean-up, separation of commercial emulsions, and solvent purification.
