In order to include fatty acids, the samples are acidified prior to extraction. Non-volatile oily material may be determined by flocculation of the ,wastewater, with an ,iron, salt, followed by extraction of the oily matter. The sample is first acidified to pH 4 and treated with an ,iron, salt to form a flocculent ferric hydroxide precipitate.
