In the fluorescence method, saturated solution was prepared by adding excess amount of pyrene to an air-tight 1 x 1 cm quartz fluorescence cell containing 5 mL salt solution. The cell was rotated at 20 rpm for at least 72 hr in a thermostated water bath and then its fluorescent intensity was measured at 395 nm. The spectrofluorimeter employed a ratio-photon counting mode where pyrene concentration was linearly related to the fluorescence signal. The UV method was used to obtain the absorptivity of pyrene in ethanol therefore provide an absolute solubility scale for the fluorescence method.", "dataset": [{"series": 1, "title": "Solubility of pyrene in 0.5 g-mol(2)/dm**3", "points": [{"pntnum": 1, "conditions": [{"property": "Ambient temperature", "number": "8.6e+00", "significand": "8.6", "exponent": "0", "sigfigs": "2", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "2.00e-07", "significand": "2.00", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 2, "conditions": [{"property": "Ambient temperature", "number": "1.22e+01", "significand": "1.22", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "2.50e-07", "significand": "2.50", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 3, "conditions": [{"property": "Ambient temperature", "number": "1.55e+01", "significand": "1.55", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "2.85e-07", "significand": "2.85", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 4, "conditions": [{"property": "Ambient temperature", "number": "1.82e+01", "significand": "1.82", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "3.22e-07", "significand": "3.22", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 5, "conditions": [{"property": "Ambient temperature", "number": "2.07e+01", "significand": "2.07", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "3.57e-07", "significand": "3.57", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 6, "conditions": [{"property": "Ambient temperature", "number": "2.30e+01", "significand": "2.30", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "3.90e-07", "significand": "3.90", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 7, "conditions": [{"property": "Ambient temperature", "number": "2.50e+01", "significand": "2.50", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "4.41e-07", "significand": "4.41", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 8, "conditions": [{"property": "Ambient temperature", "number": "2.81e+01", "significand": "2.81", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "5.19e-07", "significand": "5.19", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}, {"pntnum": 9, "conditions": [{"property": "Ambient temperature", "number": "3.11e+01", "significand": "3.11", "exponent": "1", "sigfigs": "3", "unit": "°C"}], "data": [{"property": "Amount concentration (1)", "number": "5.96e-07", "significand": "5.96", "exponent": "-7", "sigfigs": "3", "unit": "mol/L"}], "supplemental": []}]}]}}
