Tasks for October 15 New film synthesis of PVA and 10% PVA-Clay films To complete preparation of ionic modified clays To evaluate R6G stock concentration and update all data New film synthesis 1.0084 g of 22,000 MW PVA and 0.1105 g of NaMT were hydrated with 7 mL of distilled water 1.0020 g of 22,000 MW PVA were hydrated with 7 mL distilled water Heated at approx. 80ºC under gentle stirring until all crystals were dissolved Cooled to room temperature Added 0.5 mL 0.8% wt glutaraldehyde Stirred for 3 min to ensure homogeneity Poured into teflon dish Completion of ionic modified clays Completed synthesis from Oct. 3 Determination of R6G stock solution concentration Note that this is the solution that was mislabeled as 159 μM Diluted by a factor of 4000 to get a suitable fluorescence spectrum. Total area under curve = 17480.50 Using calibration curve obtained on Oct.1: <br.> Concentration of R6G stock = 1.9 mM
