文摘The indirect electrochemical reduction of Indanthrene Brilliant Green FFB （IBG） was investigated in detail by cyclic voltammetry and electrolytic experiments.Triethanolamine （TEA） was used as ligand to form elec-trochemically active Fe（III）-complexes in alkaline solution.The effects of operating parameters including reaction temperature,current density,concentration of NaOH and Fe（III）-TEA mediator had been studied by orthogonal ex-periments and the mechanism of radicals on electrochemical reduction was discussed.The cyclic voltammetry ex-perimental results show that Fe（III）-TEA complexes are well suited for the indirect electrochemical reduction of IBG.The electrolytic experiments show that high current efficiency （49.9%） can be successfully achieved under op-timized conditions and the current density is found to be the main influence factor.
