A spectrophotometric procedure has been developed for determination of oil and grease in aqueous phase. The water sample is acidified to a low pH (less than or equal to 2) and extracted with 1,1,2-trichloro-l,2,2-trifluoroethane (Freon 113, or CFC 113). Under controlled conditions, the oil and grease are extractable into a selected organic…[Read more]
