Abstract:
A method for detecting trichloroethylene (TCE) in a material, the method comprising:contacting the trichloroethylene (TCE) in the material with poly(ethylenimine); generating poly(1,4-ethylene-2-piperazone); and monitoring an intensity of infrared (IR) absorbance at 1658 cmâˆ’1, wherein the step of contacting the trichloroethylene (TCE) with the poly(ethylenimine) increases an infrared absorbance at 1658 cmâˆ’1 and an intensity of the infrared absorbance is related to an initial trichloroethylene (TCE) concentration in the material for detecting trichloroethylene (TCE).
