The spectrum of DTNB added to 10 ppm ITA was analyzed versus time at various pHs to evaluate the color change mechanism. 1.0 M Phosphate buffer was prepared and 30 mL aliquots were adjusted to the following pHs: 3, 7, 10, and 12. 22.2 uL of 1000 ppm KATHON® 886 MW was added to a semi micro cuvette followed by 2.065 mL of one of the above phosphate buffers. The solution was mixed and allowed to stand for one minute. These preparations resulted in a final isothiazolinone concentration 10 ppm.
