Students will demonstrate a method used to degrade a water pollutant. Specifically, persulfate will be used to degrade a dye (common water pollutant in the textile industry). Students will measure the dye concentration versus time to determine the decolorization rate constant. If desired, this can be done at multiple temperatures to determine the activation energy of the reaction. This activity will give a hands-on activity for students to learn how some pollutants are removed from water.
