The presence of kaolinite, montmorillonite, and illite in packed quartz sand inhibited the transport of graphene oxide to different degrees. Transport inhibition was exerted mainly by the presence of positively charged sites on clay edges (which served as favorable deposition sites), whereas the effects on the overall particle–collector interaction energy and flow path were small. Kaolinite exhibited the most significant transport‐inhibition effects because of its high percentage of edge area. Environ Toxicol Chem 2017;36:655–660. © 2016 SETAC
