text: As the pvalues of the carboxylic acid groups of lignin are below 4.6 and most of the pvalues of the phenolic groups lie above 9 (with some species with electron-withdrawing groups having a pvalue between 7.3 and 9), it can be observed that there is almost no overlap between the deprotonation of carboxylic acid and phenolic groups of lignin.
