## We are going to exchange the sodium in the sodium montmorillonite for an organic cation. The procedures are taken from these two sources ([http://www.scirp.org/journal/PaperInformation.aspx?PaperID=17245#.VA5V9Et5_zY 1], [http://www.clays.org/journal/archive/volume%2010/10-1-153.pdf 2] along with Karlena Brown's thesis. We are working from the starting point that there are 92 miliequivalents (meq) of Na+ per 100g of montmorillonite. | ## We are going to exchange the sodium in the sodium montmorillonite for an organic cation.

## | ## The original film preparation protocol was followed | ||
## | ## Began organic cation exchange following [[User:Matt_Hartings/Notebook/AU_Biomaterials_Design_Lab/2014/09/10| Dr. Harting's procedure]] | ||
## | ### 1.1046 g of Sodium Montmorillonite was added to a vial | ||
## | ### Assuming 92 meq of Na per 100 g, the total eq was 10.16232E-04 | ||
## | ### Added 0.5251 g tributylhexadecylphosphonium bromide (MW=507.65) to the vial | ||
## | ### Added 10 mL of HPLC water and 10 mL ethanol | ||
# | ### capped the vial and set to stir for one week | ||
## | ## Finished compiling and sorting through data (UV-VIS, FTIR) from last week | ||
## | ## There was not enough time to retrieve the DSC data, so this will be completed on Friday | ||
#Prepared Film Samples for Powder X-Ray Diffraction | |||
## Incised a PVA-clay film with the size of the scintillating vial lid. | |||
* | ## The film was suspended in 10 mL of 2ppm MG solution contained in a scintillating vial. The MG solution for this sample was prepared from the stock solution prepared on [[User:James C. Schwabacher/Notebook/CHEM-571/2014/08/29|August 29, 2014.]] | ||
* The sample will be analyzed for the following lab meeting on September 12, 2014. | |||
