Creating PVA Films from Exchanged Clays
Today 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 R6G
A 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
V1*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
The following chart details the initial masses of each of the films begun today.
