ObjectiveToday's objective was to repeat the bead procedure from February 14th, but instead of making a bead composite of 10% bentonite we made beads for 10% charcoal. We also tested our dried film from last week using XRD. ProtocolSynthesis of Charcoal beads
Prepping of XRD samples
ObservationsWhen packing the columns, it was easiest to scoop out some of the larger chunks that weren't beads, elute out some water, and pour a more concentrated slurry of beads into the column to save time when packing in the beads.
