Abstract:
A method for the determination of monopersulfate salts in aqueous solutions comprising:A. Contacting a test solution sample with a reagent composition comprising:a) a chromatic indicator capable of reacting with iodine to give a color change;b) a buffer to maintain the test solution and composition at a pH of 5 to 7;c) 0.01 to 0.05% iodide salt;d) 0.1 to 2.0 cationic surfactant;e) 0.1 to 2.0% of a solubilizing polymer;B. Comparing the color responses obtained to color responses from standardized solutions of monopersulfate salts and translating such comparisons to the amount of monopersulfate salt in the test solution.
