| Abstract: | The equivalence absorbency double wavelength Ultraviolet Spectrophotometry for the determination of phenol and hydroquinone is described. The determination wavelengthes are selected as 268 nm and 298 nm. The method is fast and simple. The synthetic sample was analysed by the method and the results were obtained with satisfactoriness. The relative standard deviation of phenol and hydroquinone were less than 1.2% and 0.96% respectively. The relative error of phenol and hydroquinone were less than ±0.67% and ±0.4% respectively. The detection limit of phenol and hydroquinone are 0.8 μg/mL and 0.6 μg/mL. |
