Measuring the Absorbance of Mercury and Arsenic
10 mL of each solution were poured into glass vials containing the PVA-polymer films Second Analysis of UV-Vis MG data for PVA-polymer film<br.> Used MG calibration curves obtained on Sept. 5 2014
Solving for concentration:
Note that 10 of MG solution were added per vial, so that 2 ppm MG = (1.760 mg MG/L)×0.010L=0.0176 mg MG/film <-- absorbed amount <br.> The weight of the film submerged in 2 ppm MG solution was 0.1060 g. Refer to Sept. 12 2014 for further film weights.
Measuring amount of MG absorbed onto glass vial<br.> As in previous section, the molar absorptivity and calibration curve from Sept. 5 2014 were used. <br.> 80 ppm MG in glass vial control: 42.87 ppm were absorbed by glass (Calculations as show in previous section)
200 ppm MG in glass vial control: 88.63 ppm were absorbed by glass
