This work focused on creating a colorimetric sensor to detect trihalomethanes (THMs) at concentrations near the level of environmental regulations from the environmental protection agency (EPA). This work utlized the fujiwara reaction as well as a hydrophobic electrospun polyprolylene membrane to produce a sensitive colorimetric reaction. A calibration curve was produced which was able to predict the concentration of a bromoroform solution in the range of 8-250 ppb with a confidence of 97.7 % using the intensity of the color change as a quantitative measure.
