A method for determining the concentration of isothiazolones in an aqueous system comprising: (a) mixing a known volume of solution to be analyzed with a volume containing a known quantity of aromatic thiol salts which form colored solutions for a specified period of time; (b) determining color of the resultant solution; and (c) comparing the color to a standard of known concentration. This invention is especially applicable to cooling towers and in the metal working industry and for fuel.
