The use of nonvolatile, edible triglycerides for the removal of trace organic materials from water was investigated. All organic substances that were studied were readily removed from water by contact with triglycerides. Solvent extraction with liquid soybean oil reduced the concentrations of benzene and chloroform in water. A fixed bed filter of liquid soybean oil, hydrogenated palm oil and sand removed toluene and chloroform from water. Toluene was removed from water by adsorption with hydrogenated palm oil, a solid fat. |
