| 摘 要： | 研究了对二巯基苯对染料的芬顿降解反应的影响. 研究发现,对二巯基苯可以显著加速孔雀绿和罗丹明B等有机染料的芬顿降解,但是不能提高染料的矿化率. 通过循环伏安和邻菲啰啉实验,确认对二巯基苯在芬顿反应中的助催化剂作用是通过加速Fe3+/Fe2+的循环实现的. 将对二巯基苯和氢醌的助催化效果做了比较.

| Abstract: | In this study, we have found that the presence of 1,4-benzenedithiol (SH) could greatly accelerate Fenton reaction of dyes, such as malachite green and Rhodamine B, but could not improve the mineralization of those dyes. By performing cyclic voltammetry and 1,10-phenanthroline experiments we confirm that the effect of SH as a co-catalyst in the Fenton reaction is based on the accelerated cycle of Fe3+/Fe2+. We compare the effects of 1,4-benzenedithiol and 1,4-hydroquinone. |
