== | ==Continuation of Ionic Liquid Exchange Clay== | ||
* | * Dr. Hartings completed the washes for the Ionic Exchange Clay from last Wednesday, Sept. 19, 2014. | ||
* The clay was spread on a watch glass to dry. | |||
* As the film dried, a spackle-like texture was observed. | |||
* The solid was scraped off from the watch glass and ground into a mortar and pestle. | |||
* The ground solid weighed in the amount of 1.04572 g; this was transferred into a scintillating vial. | |||
* The exchanged clay material was stored by Dr. Hartings in an oven to evaporate excess water in the solid. | |||
==Film Synthesis== | |||
* PVA Film | |||
** 1.0005g PVA | |||
*PVA-Clay Film | |||
** 1.0117g PVA + 0.1105g Clay | |||
==Analysis of PVA-malachite green data== | |||
* I prepared an [http://openwetware.org/wiki/Image:PVA_MJJ.xlsx MS Excel workbook] containing the calculations for the grams of malachite green absorbed per gram of film. | |||
==Film Suspension in Arsenic and Mercury== | |||
* Data below were taken from James Schwabacher's [[User:James C. Schwabacher/Notebook/CHEM-571/2014/09/19|entry]]: | |||
*Mercury stock solution | |||
# 0.0908g HgCl2 | |||
## (0.0908g HgCl2)*(1mol HgCl2/271.5g HgCl2)*(1mol HgCl2/1mol Hg)*(200.59g Hg/1mol Hg) = 0.0671g Hg | |||
## put in 250mL volumetric | |||
## 268ppm Hg | |||
*Arsenite solutions for vials from 0.0499 mol/L (3738.588 ppm As) stock. These were made by me and Eleni for the entire class. | |||
# 4 mL of stock in 100 mL volumetric flask -> 150 ppm As | |||
# 2.67 mL of stock in 100 mL volumetric flask -> 100 ppm As | |||
# 1.337 mL of stock in 100 mL volumteric flask -> 50 ppm As | |||
*Mercury solutions for vials from 268 ppm Hg stock. These were prepared by me and Madeleine, to split between our groups. | |||
# 27.985 mL of stock in 50 mL volumetric flask -> 150 ppm | |||
# 18.657 mL of stock in 50 mL volumetric flask -> 100 ppm | |||
# 9.328 mL of stock in 50 mL volumteric flask -> 50 ppm | |||
