摘要：
Biochar is an effective adsorbent commonly used in pollutants adsorption. However, natural constituents, such as dissolved organic matter (DOM), could affect pollutants adsorption. In this study, we analyzed the mechanisms underlying phenol adsorption on pine biochar under perturbation by fertilizer-derived DOM. In addition, biochar property alterations were characterized and further analyzed. The results showed that phenol and DOM com-bined to a certain extent in the adsorption system. DOM affected the adsorption pathway, which increased the biochar adsorption efficiency for phenol. The addition of DOM2 promoted phenol adsorption efficiency (70.31%), with total DOM adsorption capacity of 61.45 mg g-1 onto biochar.
