Objective
- Continue processing films from last week
- Make two new films
- One containing the exchanged clay that your group made
- 0.9995g of PVA with 0.1107g of 1-hexadecyltriphenylphosphonium bromide
- One containing the exchanged clay that another group made
- 1.0022g of PVA with 0.1111g of tributylhexadecylphosphonium bromide used from Michael's group
- Run AA on the arsenic samples
- Make As standards (Note: AA will consume around 5mL of sample)
- 0ppm
- 10ppm
- 20ppm
- 30ppm
- 40ppm
- 50 ppm
- Dilute your samples so that their original concentration falls somewhere in this range.
- Make calibration curve and determine the concentration of As using AA.

Preparation of solutions
- 1uM R6G - 0.629mL of stock into 100mL
- 10uM R6G - 6.289 mL of stock into 100mL
- 20uM R6G - 12.578 mL of stock into 100mL
- Due to a error in the labeling of the stock solution the actual original concentration was 1.9mM which means that based off the volume of the stock used the actual concentrations were
- 11.95uM - instead of the 1uM
- 119.49uM - instead of 10uM
- 238.9 uM instead of 20uM
