passing the aqueous solution, comprising a hydrophobic organic substance, over or through a surface comprising a polystyrene-carbon nanofiber (CNF) composition, thereby producing an aqueous product comprising less of the hydrophobic organic substance,
wherein a polystyrene of the polystyrene-CNF comprises post-consumer waste collapsed polystyrene foam,
wherein a CNF of the polystyrene-CNF is associated with the polystyrene by sonicating a mixture of the CNF and the polystyrene in softened or collapsed form,
wherein the post-consumer waste polystyrene is contaminated with sugar, starch, protein, nucleic acid, lipid, other food component, paint, ink, dye paper, or non-polystyrene plastic contaminant, in a range of from 0.001 and 5 wt. %.
