| Abstract: | The charge transfer reaction between taurine and benzoquinone was investigated by spectrophotometry.The stable charge transfer complex was formed by taurine and benzoquinone inpH 8.5 Britton-Robinson buffer solution with heating in water bath of 90℃ for 20min.The composition ratio of the complex of taurine with benzoquinone was 2∶1.The apparent molar absorptivity of the complex was 5.9×104L/mol·cm with maximun absorbance wavelength of 339nm.The charge transfer complex obeyed Beer＇s law in the concentration range of 4—180μg/mL,and the recovery was in the range of 96.1%—101.8%.The relative standard deviation was less than 3.0%.This proposed method is applied to the determination of the content of taurine in capsule and granule with satisfactory results. |
