ABSTRACT:
This invention provides a method for determining the concentration of a brine tolerant sulfonate surfactant in a complex mixture containing, in addition to said brine tolerant sulfonate surfactant, lignosulfonates, crude oil, salts, and water and, optionally, petroleum sulfonates and alcohols, that comprises incorporating into the brine tolerant sulfonate surfactant molecule a small amount of tritium prior to addition to the complex mixture and determining the concentration of the brine tolerant sulfonate surfactant by measuring its radioactivity.
