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. Copyright@ International Science Community Association
