Abstract: An apparatus and method for measuring hydrogen peroxide concentration in water to an accuracy of 0.1 ppm comprises a colorimetric assay method to determine hydrogen peroxide concentration. The assay is monitored spectophotometrically at a desired wavelength. Each sample is corrected relative to a control sample and hydrogen peroxide concentration determined with respect to a standard curve.
