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.
- PVA Film
- PVA-Clay Film
- 1.0117g PVA + 0.1105g Clay
Analysis of PVA-malachite green data
- I prepared an 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 entry:
- 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
