| 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. |
