ABSTRACT:
The present invention provides for a method and system for determining the concentration of a surfactant in a transparent hydrocarbon by performing the steps of adding a solid to the hydrocarbon; adding a second masking reagent to the hydrocarbon; mixing to form a dispersion; separating the dispersion from the mixture; and measuring the optical absorption of the dispersion.
