Abstract: An embodiment provides a method for measuring sulfate in an aqueous sample, including: introducing an aqueous sample containing an amount of sulfate to a barium dye complex, thereby creating a solution; adding a clarifying agent to the solution, thereby causing the solution to be clarified; and measuring the amount of sulfate in the aqueous sample by measuring a change in color of the solution, the change in color caused by the barium dye complex mixing with the sulfate. Other aspects are described and claimed.

Abstract: An embodiment provides a method for measuring an analyte component of an aqueous sample, including: introducing an indicator solution to the aqueous sample, wherein the indicator solution comprises a plurality of micelles, wherein an indicator is within the micelles and the plurality of micelles is assembled from a cationic surfactant to form an indicator solution; and measuring an analyte component concentration of the aqueous sample, wherein the measuring comprises measuring a change in fluorescence in the aqueous sample, wherein the change in fluorescence is responsive to the analyte component interacting with the indicator. Other aspects are described and claimed.
