Objectives
- Finish standards prep(1-1/50 of 20ppm stocks, 4-6standards for each)
- Add NaMT to CuSO4 blue solution prepared on 09/21/2012
- Prepare solutions for atomic absorption analysis:
*NaMT-CuSO4 exchange solution
*100% CEC (Bu3HdP+)-MT surfactant clay-CuSO4 exchange solution
*50% CEC (Bu3HdP+)-MT surfactant clay-CuSO4 exchange solution
- Prepare films:
*1.0gPVOH+0.1g NaMT+0.8wt% glutaraldehyde
*1.0gPVOH+0.1g 100% CEC (Bu3HdP+)-MT surfactant clay+0.8wt% glutaraldehyde
CuSO4 exchanged solutions
General Protocol:
- Pour 20mL of CuSO4 stock solution(prepared on 09/21/2012) into a clean beaker with a magnetic stirrer.
- Stir solution breifly(~1min)
- Add 0.1g clay to solution while solution is stirring. Immediately start a timer.
- Allow solution to stir for desired amount of time(for this experiment the time intervals 1min, 5min, and 10min will be used).
- Once the time period has ended, immediately filter the solution with a dry 42 Whatman filter paper
- Note: Make sure that all glassware is clean and dry. To ensure that the glassware is dry, rinse the glassware with acetone and place in an oven(~60°C) for ~5min to dry.
