The present application discloses methods for detecting and quantifying tetrakis(hydroxymethyl) phosphonium sulfate (THPS) in a water sample. In the methods, a water sample is mixed with a KMnOsolution to form a mixture. An intensity of KMnOabsorption in the mixture is then measured at a wavelength of 525 nm. The measured intensity is normalized by subtracting a background intensity at a wavelength of 650 nm. The presence and concentration of THPS in the water sample can then be determined by comparing the normalized intensity with intensity values of KMnOabsorption of calibration samples comprising KMnOand known THPS concentrations.
