Objective
Finish making ICP PVA/clay samples with Pb and make clay MG samples for UV-Vis analysis to complete last semesters paper.
Lab Protocol
For metal uptake samples use about 5 grams of metal solution and 50 mg of PVA/clay beads.

Notes
Note from 2/22/19, was not able to properly separate the clay from the MG, so samples were not usable. Will retry in future.
