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.
Description
- Add experimental record here. Include what, how, and why...
