This work will investigate the correlation between cyanuric acid concentration and established industry hardness testing methods. In addition, a correlation between cyanuric acid concentration and dissolution rates of actual disinfected swimming pool water will also be established. Swimming pool water will be provided from the home and it will be tested using researcher’s conventional techniques for pH, free chlorine, total alkalinity, hardness and acid demand. Water samples will be prepared with various known concentrations of cyanuric acid, in deionized water, along with test samples from the swimming pool which will contain sodium hypochlorite (bleach) and cyanuric acid. These samples will be analyzed using a gas chromatograph to create a concentration curve. Chemicals used: DI Water Cyanuric acid Sodium hypochlorite Equipment used: Stirring hot plate Analytical balance 1 liter plastic bottles with caps GC vials appropriate for the instrument used Thermofisher Gas Chromatograph with auto-sampler
