AbstractRedox-active quinone and nonquinone moieties represent the electronexchange capacity (EEC) of natural organic matter (NOM), playing an importantrole in the electron transfer link of microbes and transformation of contaminants/metal minerals. However, the corresponding transformation of quinone/phenol andtheir respective influence on the EECs during reduction and reoxidation remainpoorly characterized. Besides, it is still controversial whether nonquinones donate oraccept electrons. Herein, we demonstrated that reoxidation of NOM after reductioncan form new phenolic/quinone moieties, thus increasing the EEC. The assessmentfor the EEC, including the electron-donating capacity (EDC) and electron-acceptingcapacity (EAC), of nonquinones reflects the contribution of sulfur-containingmoieties with considerable EDCs and EACs. In contrast, nitrogen-containing moieties donate negligible electrons even atEh= +0.73V. The contributions of both thiol and amine moieties to the EEC are greatly affected by adjacent functional groups. Meanwhile,aldehydes/ketones did not display an EAC during the electron transfer process of NOM. Furthermore, substantially increased EDCatEhfrom +0.61 to +0.73 V could not be fully explained using thiol and phenolic moieties, suggesting the contribution of unknownmoieties with high oxidation potential. The overallfindings suggest that the roles of new quinones/phenol (derived from theaddition of oxygen to condensed aromatic/lignin-like components) during redox dynamic cycling and thiol species should beconsidered in assessing the electron transfer processes of NOM
