Fig. 1: DOC and numbers of Fenton-derived DOM molecules after individual monomer reactions and mixed monomer reactions of different DOM species.

Monomers of different DOM species were used for the reactions (Supplementary Table 1). The reaction duration was 60 min for both the individual monomer reaction and the mixed monomer reaction. a The statistical results of the mean effluent DOC from triplicate tests for individual monomer reactions for each DOM species, where the DOC kinetic degradation changes of all reactions were shown in Supplementary Fig. 1. The bar + data overlap plot shows the median (bar), whiskers representing 1.5 × the interquartile range, and outliers as points beyond the whiskers. b The statistical results of the number of Fenton-derived DOM for individual monomer reactions for each DOM species, where the results for each monomer were shown in Supplementary Fig. 2. The bar + data overlap plot shows the median (bar), whiskers representing 1.5 × the interquartile range, and outliers as points beyond the whiskers. The vertical axis represents absolute number. c The effluent DOC of mixed monomer reactions for each DOM species, where the results of triplicate tests for DOC were shown. The bar + data overlap plot shows the mean (bar), error bars representing standard deviation from triplicate tests. In addition, the DOC kinetic degradation changes of all reactions were shown in Supplementary Fig. 1. d The number of Fenton-derived DOM for mixed monomer reactions of each DOM species. The symbols and bars represent the same values. The vertical axis represents absolute number. The significant differences for statistical hypothesis tests in all panels were labeled using the letter labeling method. The methods and p-values for statistical hypothesis tests in all panels were shown in the Source Data file.
