Partitioning of hexachlorobenzene in a kaolin/humic acid/surfactant/water system: Combined effect of surfactant and soil organic matter

► We study HCB partitioning in a kaolin/humic acid/TX100/water system. ► We reveal influence of TX100-HA interaction on TX100 and HA sorption to kaolin. ► We verify combined effect of TX100 and HA on HCB desorption from clay.
