In this study, 15 VOCs were probed to determine their gas/solid partitioning coefficient (Log Kd) using inverse gas chromatography at different relative humidity (RH) levels. Interactions between MWCNTs and VOCs were analyzed by regressing the observed Log Kd with the linear solvation energy relationship (LSER). The results demonstrate that the MWCNT carbonyl and carboxyl groups provide high adsorption capacity for the VOCs (Log Kd 3.72-5.24 g/kg/g/L) because of the π-/n-electron pair interactions and hydrogen-bond acidity. The increasing RH gradually decreased the Log Kd and shifted the interactions to dipolarity/polarizability, hydrogen-bond basicity, and cavity formation. The derived LSER equations provided adequate fits of Log Kd, which is useful for VOC-removal processes and fate prediction of VOC contaminants by MWCNT adsorption in the environment.Hydrogen-bondLinear solvation energy relationshipMultiwall carbon nanotubesRelative humidityVolatile organic compounds[SDGs]SDG6journal article10.1016/j.jhazmat.2016.04.0042-s2.0-84968912293https://www2.scopus.com/inward/record.uri?eid=2-s2.0-84968912293&doi=10.1016%2fj.jhazmat.2016.04.004&partnerID=40&md5=356459b8b6cd06f4566f359a0f7c45aa
