  "abstract": "Biomass-derived adsorbents are increasingly used for aqueous pollutant removal, yet adsorption mechanisms are often inferred from model fitting or isolated characterization rather than convergent molecular evidence. This scoping evidence review integrates experimental surface chemistry, density functional theory (DFT), molecular dynamics (MD), and machine learning (ML) to examine the transition from mechanistic interpretation to transferable prediction. Using a PRISMA-ScR-informed systematic evidence mapping approach, a relevance-prioritized analytical corpus of 125 primary studies was constructed, comprising 70 mechanistic and 55 predictive studies. Evidence charting was closed after the mechanistic and predictive categories stabilized during relevance-prioritized synthesis. Electrostatic interactions, hydrogen bonding, surface complexation/coordination, π interactions, and pore filling were the most recurrent mechanisms and frequently coexisted. Static adsorbate–surface DFT predominated, whereas solvent/speciation-aware calculations and dynamic interfacial models remained comparatively limited. The synthesis shows that kinetic or isotherm fitting cannot uniquely establish molecular mechanisms and that ML feature importance or SHapley Additive exPlanations (SHAP) attribution should not be interpreted as causal evidence. Predictive transferability was more convincingly demonstrated through grouped, external, or experimental validation than through random data partitioning. Based on these findings, we propose the Molecular Mechanistic Evidence Framework (MMEF), integrating molecular depth, evidence convergence, environmental realism, interpretive discipline, and predictive transferability to guide adsorption research toward molecularly supported, experimentally testable, and prospectively predictive adsorbent design.",
