Abstract
Brilliant blue FCF disodium salt of 4-(4-N-ethyl-m-sulphohenzyl aminophenyl] 12-sulphonium phenyl)-methylenes [1-(N-ethyl-N-m-sulphobenzyl)-Δ 2 - 5 -cyclohexadienimine is a certified colourant used by various pharmaceutical companics. In the present work, the study of electrochemical behaviour was carried out and feasibility of controlled potential electrolysis technique is judged in terms of rate of disappearance of colour, decrease in absorbance, disappearance of any reduction peak in decolourised solution, decrease in COD value which were chosen as parameters to evaluate the progress of reduction. The decomposition products of controlled potential reduction were characterised by spectrophotometric and chromatographic method. This method of dye degradation is useful in identifying the reduction pathway and provides potential for dye degradation.
