Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Pyrene; C16H10; [129-00-0]  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) Regent grade
   (3) Distilled from potassium permanganate-sodium hydroxide and passed through an XAD-2 column.

Estimated Errors:
   Solubility: K_s ± 0.003; S_o ± 0.001
   Temperature: ± 0.05 °C
