Tasks for November 12

  • To measure MG green absorbance by activated carbon and zeolite.

Activated carbon

  • 0.1 g of activated carbon were added to scintillation vials.
  • Soaked in 10 ml of 23.3 ppm malachite green solution.
    • 23.3 ppm MG dye solution was made by James and Eleni.
  • Centrifuged and extracted.

Note: This method was dropped because activated carbon absorbs almost immediately. Will try new method on Friday using 0.01 g of activated carbon, and filtration instead of centrifuge.
