#One group will use a PVA film | |||
#*The other group will use a PVA/clay film | |||
#Set the film between the two chambers | |||
#Add liquid to each chamber | |||
#*One chamber gets water | |||
#*The other chamber gets 20ppm Malachite green | |||
#Withdraw 200uL from each chamber at the 5 minute mark and place in their own eppy tube | |||
#*NOTE: I want the groups to coordinate so that their 5 minutes don't overlap with one another. | |||
#*NOTE: You'll want to use a small volume cuvette | |||
#*NOTE: You'll also want a 0minute measurement for each. | |||
#*NOTE: You'll likely have to dilute the sample from your chamber with the 20ppm. So, when you return the sample, only return the non-diluted sample. | |||
#Measure the UV-Vis spectrum for both samples. Return each to the chamber it originally came from | |||
#Take measurements at the following times | |||
#*15 minutes | |||
#*30 minutes | |||
#*1 hour | |||
#*2 hours | |||
#*right before you leave lab | |||
*It would be great if someone could stop by on Thursday to take a measurement then. | |||
*You'll be taking measurements on Friday too. | |||
*During each of this, it would be best to start working up the data right away. | |||
