摘要：

A novel and convenient method with good selectivity and high sensitivity for the determination of hydroquinone (HQ) based on the Belousov-Zhabotinskii (B-Z) oscillating chemical reaction has been presented. The optimum condition for the determination has also been investigated. In the B-Z reaction system, when the sample was injected. the change of the amplitude is linearly proportional to the logarithm of the concentration of HQ in the range 1.0 x 10(-2) -2.0 x 10(-4) M (r = 0.9965), whereas, when the concentration of HQ is over the range from 2.5 x 10(-4) to 4.0 x 10(-7) M, the calibration curve fits a second-order polynomial equation very well (r = 0.9983).
