The mobility and distribution of heavy metal ions (HMs) in aquatic environments are significantly influenced by humic acid (HA), which is ubiquitous. A quantitative understanding the interaction mechanism underlying adsorption retention HMs HA vital significance but remains elusive. Herein, between different types (i.e., Cd(II), Pb(II), arsenate, chromate) was quantitatively investigated at nanoscale. Based on quartz crystal microbalance with dissipation tests, capacities As(V), Cr(VI) ionic species surface were measured as ∼0.40, ∼0.25, ∼0.12, ∼0.02 nmol cm–2, respectively. Atomic force microscopy results showed that presence Pb(II)/Cd(II) cations suppressed electrostatic double-layer repulsion during approach two surfaces adhesion energy separation considerably enhanced from ∼2.18 to ∼5.05/∼4.18 mJ m–2. Such strong stems synergistic metal–HA complexation cation−π interaction, evidenced spectroscopic analysis theoretical simulation. In contrast, As(V)/Cr(VI) oxo-anions could form only weak hydrogen bonds HA, resulting similar energies for HA–HA (∼2.18 m–2) HA–As(V)/Cr(VI)–HA systems (∼2.26/∼1.96 m–2). This work provides nanoscale insights into HM–HA interactions, improving biogeochemical cycling.
