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.

Data

Pb(C2H3O2)2 (ppm) beads (mg) Pb(C2H3O2)2 (g)

5.176 51.6 5.59
1.275 49.8 5.23
0.16 49.4 5.02
0.584 49.9 5.21
Na-Montmorillonite (g) Starting MG (ppm) MG (g)
0.1034 25.0 5.0191
0.1007 49.977 4.9966
0.1009 74.9 5.0385
0.1033 98.7 4.9944
0.1041 247.0 5.0664

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.
