Activated carbon is employed for the adsorption of organic micropollutants(OMPs)from water,typically present in concentrations ranging from ng L1 to mg L***,the efficacy of OMP removal is considerably deteriorated due to competitive adsorption from background dissolved organic matter(DOM),present at substantially higher concentrations in mg L*** the characteristics of competitive DOM is crucial in predicting OMP adsorption efficiencies across diverse natural *** weight(MW),aromaticity,and polarity influence DOM *** the aromaticity-related metrics,such as UV254,of low MW DOM were proposed to correlate with DOM competitiveness,the method suffers from limitations in understanding the interplay of polarity and aromaticity in determining DOM ***,we elucidate the intricate influence of aromaticity and polarity in low MW DOM competition,spanning from a fraction level to a compound level,by employing direct sample injection liquid chromatography coupled with ultrahigh-resolution Fouriertransform ion cyclotron resonance mass *** exchange resin pre-treatment eliminated 93%of UV254-active DOM,predominantly aromatic and polar DOM,and only minimally alleviated DOM *** characterization revealed that nonpolar molecular formulas(constituting 26%PAC-adsorbable DOM)with medium aromaticity contributed more to the DOM *** analysis indicated that the competitiveness of highly aromatic LMW DOM compounds was strongly counterbalanced by increased *** aromaticity-derived p-p interaction cannot facilitate the competitive adsorption of hydrophilic DOM *** results underscore the constraints of depending solely on aromaticity-based approaches as the exclusive interpretive measure for DOM *** a broader context,this study demonstrates an effect-oriented DOM analysis,elucidating counterbalancing interactions of DOM molecular properties
