Abstract
Methods for quantitative determination of the presence of isothiazolone compounds in a solution include controlling pH of the solution in a range from about 3 to about 10, combining a known quantity of the pH-adjusted solution with a known quantity of an aromatic thiolate anion, quantitatively determining color intensity of the resultant combined solution; and correlating the color intensity with amount of isothiazolone compounds. The methods may be used in automated systems, including systems utilizing optical sensor devices.
