Comparison of Extractive Capacities of Systems Based on Sulfonol, Sodium Dodecyl Sulfate, or Alkyl Benzene Sulfonic Acid

Effect of organic complexing reagents: diantipyrylmethane, diantipyrylbutane, diantipyrilheptane, 1,10-phenanthroline, and 1,2,3-benzotriazole, on the phase state and extractive capacity of systems containing anionic surfactants: sulfonol, sodium dodecyl sulfate, or alkyl benzene sulfonic acid as a phase-forming agent and an inorganic acid (sulfuric or hydrochloric) as a salting-out agent. The optimal conditions were found for all the combinations under study of a surfactant and a reagent to be used in the separation and concentration processes. The most extraction-effective surfactant—reagent combinations were chosen.
