      abstract     = {The material and enthalpy balances of the adsorption of
                      sodium n-decyl sulfate from aqueous solutions onto
                      graphitized carbon black were determined between 288 and 318
                      K by using an automated flow sorption/microcalorimeter
                      system. At low concentrations, the surfactant molecules form
                      a flat monomolecular film on the graphite plane, in
                      consequence of surface-directed ordering. A mechanism is
                      proposed in which two adsorbed phases coexist during the
                      formation of this surfactant monolayer. The enthalpy of
                      adsorption in the monolayer region is ca. -42 kJ mol(-1),
                      which does not depend appreciably on the temperature or on
                      the surface coverage. At higher concentrations, the ordered
                      monolayer induces surface aggregation to produce
                      half-cylindrical hemimicelles as the critical micelle
                      concentration is approached. The enthalpies of surface
                      aggregation at 288, 298, and 318 K are -10, -16, and -26 kJ
                      mol(-1), respectively. As the temperature is increased from
                      288 to 318 K, the average number of surfactant molecules in
                      the cross section of a half-cylinder drops from ca. 5.4 to
                      3.4. Calorimetric evidence is provided that cationic and
                      anionic surfactant adsorption on graphite follow the same
                      mechanism in the low-density and high-density adsorbate
                      regions.},
