Abstract
The disclosure relates to a method for quantitatively measuring concentration in an aqueous solution of a water soluble polymer that is functionalized with at least one tracer, wherein the method involves impregnating a flow assay with a test area, introducing the flow assay into a test reader, and using the test reader to compare test data to a calibration curve so as to determine the concentration of the water-soluble polymer. This method allows the determination of residuals concentration in aqueous solution recovered from different industries, including oil and gas produced water, mining fluids, industrial water systems, and water treatment applications.
