title: [Effect of Non-dissolved Quinone on Perchlorate Reduction by Strain GWF].
abstract: The perchlorate reduction lag phase of the strain GWF (KM062029) was shortened by using non-dissolved quinone. nthraquinone, 1-chloroanthraquinone, 1,5-dichloroanthraquinone, 1,8-dichloroanthraquinone and 1,4,5,8-tetrachloranthtaquinone were the five non-dissolved quinones in this study. The results showed that the accelerating order was 1,5-dichloroanthraquinone > 1,4, 5,8-tetrachloroanthtaquinone > 1,8-dichloroanthraquinone > Anthraquinone > 1-chloroanthraquinone. The optimal concentration of 1,5- dichloroanthraquinone, temperature and pH for perchlorate reduction were 0.036 mmol · L⁻¹, 35 °C and 7.5, respectively. The concomitant anions (nitrate, phosphate, sulfate) were in favor of the perchlorate reduction by strain GWF. After four times of recycling experiments, the accelerating perchlorate reduction rate with the immobilized 1,5-dichloroanthraquinone maintained above 2 times.
