The organic pigment that is not a carotenoid is a chlorophyll. The purified organic pigment is b-carotene, astaxanthin, zeaxanthin, carotenoid or chlorophyll (preferred). The nanomaterial is a carbonaceous nanomaterial.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The water-immiscible solvent is carbon tetrachloride, chloroform, cyclohexane, 1,2-dichloroethane, dichloromethane, diethyl ether, dimethyl formamide, ethyl acetate, heptane, hexane, methyl-tert-butyl ether, pentane, toluene or 2,2,4-trimethylpentane. Preferred Composition: The composition comprises at least 10 wt.% of carbonaceous nanomaterials. The nanomaterial is a carbonaceous nanomaterial. The nanomaterial comprises carbonaceous nanoparticles, where the smallest dimension of the carbonaceous nanoparticles is less than 500 nm, preferably 100 nm. The nanoparticles (at least 50%) are a material other than a carbon nanotube. The carbonaceous nanomaterial comprises at least 10 wt.%, 30 wt.%, 50 wt.%, 70 wt.%, 90 wt.%, or 99.9 wt.% of graphene. The nanomaterial has the capacity to bind an amount of contaminant equal to: at least 50 wt.% of the nanomaterial; or at least 10 times the weight of nanomaterial. The portion of the carbonaceous material has a tubular or spheroid configuration. The composition is substantially free of any plant pigments, or solvents. The nanomaterial comprises graphene. The composition has less than 15 wt.% water. The lipid-containing oil product contains: less than 10% or less than 5% of the chlorophyll in the crude extract; and less than 20% of the carotenoid. The further purified lipid-containing oil product is substantially free of carotenoid. EXAMPLE - Dunaliella salina algae in an aqueous saline solution at an initial concentration of 1 g/l on a dry basis was harvested using centrifugation. The resulting aqua-algae solution, containing 30% algal mass, was dried by exposure to sunlight for 10 hours to remove all moisture. The dried algal mass was contacted with hexane in a ratio of 20:1, hexane to algal mass. After approximately 1 minute, the lipophillic phase was extracted in the hexane, as confirmed by the deep green pigmentation of hexane after contacting the biomass. The resulting crude algal extract consisted of a hexane/lipid phase, which also contained dissolved pigments (chlorophyll molecules), beta-carotene and triglycerides. The crude extract was separated from the residual biomass via filtration. The filtered hexane/lipid phase was contacted with graphene in a ratio of 10 mg of graphene per ml of solution. After 5 seconds of contacting time, the hexane/lipid phase was adsorbed by the graphene. The graphene was centrifuged and a clear liquid oil product was released. The clear liquid phase consisted in a lipid-rich hexane solution lacking residual plant pigments, and was confirmed by the clear change in color. The remaining hexane was successively removed using evaporation to obtain purified oil. The final purified oil phase was substantially free of both solvent and residual plant pigments.
