Abstract

AbstractStudies examining the adsorption/desorption characteristics of chloroform to New Jersey coastal plain aquifer solids were performed. Adsorption to the Cohansey aquifer solids, a coarse‐to‐fine‐grade sand with a 4.4% organic matter content (2.6% organic carbon content), and to the Potomac‐Raritan‐Magothy aquifer solids, a sandy loam with a 2.2% organic matter content (1.3% organic carbon content), was found to be dependent on adsorber mass. Equilibrium adsorption could be characterized by either linear or Freundlich isotherms. Greater adsorption was achieved to the Cohansey material, which was attributed to its greater organic matter (carbon) content. Calculated normalized organic carbon partition coefficients were compared with values obtained from literature correlations. Consecutive desorption experiments displayed an apparent hysteresis.
