The pulp and paper industry post oxygen stage effluents containing high percent of colour causing lignin and degraded lignin compounds have been analyzed using a combination of U.V-Visible, FTIR and 13C NMR spectroscopy. The colour is mainly due to the presence of chromophoric groups in these compounds. The post oxygen effluent mainly contains lignin fragments and the possible compounds present may be vanillin, syringaldehyde , p-hydroxy benzaldehyde, vanillic acids, syringic acids, p-Hydroxy benzoic acid, fervilic acid and p-coumaric acids. The chromophoric groups can be oxidised by ozone treatment for the reduction of colour efficiently.
