Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Naphthalene; C10H8; [91-20-3]  NIST Chemistry WebBook for detail
   (3) Sodium chloride; NaCl; [7647-14-5]  NIST Chemistry WebBook for detail

Original Measurements:
   

Variables:

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   A saturated solution of (1) was prepared by pumping salt water through a "generation column" which was packed with glass beads coated with 1% by weight of (1). The saturated solution was extracted with an "extractor column" packed with a superficially porous bonded C₁₈ stationary phase, then a water-acetonitrile solvent was passed through for extraction. The extract was introduced into a liquid chromatograph and the concentration of (1) was measured with a UV detector.

Source and Purity of Materials:
   (1) greater than 97% pure
   (2) reagent grade.
   (3) distilled from potassium permanganate-sodium hydroxide and passed thrugh an XAD-2 column.

Estimated Errors:
   Solubility: K_s ± 0.001; S_o ± 0.23
   Temperature: ± 0.05°C
