Tasks for October 22 To analyse films in Bisphenol A (BPA) To finish film synthesis from Oct. 17 To finish measuring density of films (Reported on 17/10 Notebook entry) Completion of film synthesis Placed film in sodium sulfate, 1% HCl and sodium bicarbonate. Measuring absorbance of films in BPA Soaked PVA-Clay polymer films in 10.4 ppm BPA and allowed to soak for a determined amount of time ( two scintillation vials for each time slot), after which time films were removed to avoid further absorption of PBA. 10/22 5 min 10/22 15 min 10/22 30 min 10/22 60 min 10/22 120 min 10/22 240 min 10/22 afternoon 10/23 morning 10/23 afternoon 10/24 Note that the 10.4 ppm BPA solution was made by James and Eleni James measured out 10.4 mg of BPA and dissolved in 5 mL of methanol, then diluted to 1 L with distilled water.
