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.

Key words: 1,4-benzenedithiol, malachite green, iron cycle, o-quinone
