【Abstract】 A determination of phenathrene in crude anthraquinone by UV Spectrophotometer has been studied. Cyclohexane is applied as solvent and wavelength of the determination is 293 nm. The method has the precision of 2.70% RSD. The average recovery is 101.52% with RSD of 2.59%. The method is characterized by simplicity,quick determination and better repeatability, and can be used for the determination of phenathrene in crude anthraquinone.更多还原
