Creating PVA Films from Exchanged ClaysToday we made films using the cation exchange clays begun on September 10. One of the films was made using the tributylhexadecylphosphonium bromide that our group started on 9/10 and the other was made using (1-hexadecyl)triphenylphosphonium bromide that Eleni's group started synthesizing on 9/10. Our cation exchanged clays were made as follows:
Soaking PVA Films and PVA+Clay Films in R6GA new experiment (using the protocol from 8/29) was begun today using 1 μM, 10 μM, and 20μM R6G solutions instead of Malachite Green solutions.
Preparation of solutions
CalculationsV1*C1 = V2C2 V1 = V2C2/C1 Vstock = (100 mL)(1μM)/159μM) = 0.629 mL Vstock = (100 mL)(10μM)/159μM) = 6.289 mL Vstock = (100 mL)(20μM)/159μM) = 12.578 mL DataThe following chart details the initial masses of each of the films begun today. NotesAdd notes here.
