# | # Finishing the analysis of the PVA-Malachite green data, our data is being compiled into a spread sheet with other groups | ||
# Learning how to extract and interpret the data from the XRD. Data to come | |||
# New PVA and PVA clay films were started | |||
## The procedure for the film synthesis may be viewed [[User:Jacob_Esenther/Notebook/581/2014/08/27|here]]. | |||
### the initial teflon dish containing the PVA film was contaminated with malachite green. The film turned blue and we had to redo the synthesis. | |||
# Set up for arsenic and mercury absorbance experiment | |||
## Vials were labeled and weighed out with no lid | |||
## Films were cut using a falcon tube and spatula | |||
### Note: The PVA only film seems to soften the longer it soaks in water. | |||
## Vials were weighed again with films present. | |||
## Dilutions of 50ppm, 100ppm and 150ppm of Arsenic and Mercury were created. | |||
