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.
