Objective

Make PVA/clay uptake with Pb and Hg solutions for ICP analysis.

Lab Protocol

Measure 50 mg of PVA/clay beads and 5 g of Pb or Hg stock solution into a 15 mL falcon tube. Allow to sit for 1 week before analysis after 2 minutes of centrifugation at 1500 rpm.

Data

HgCl2 (ppm) beads (mg) HgCl2 (g)
15.125 51.2 5.12
10.189 52.5 5.1
5.399 50.3 5.05
1.126 51.0 4.87
0.612 50.4 5.18
0.153 51.2 5.13

Notes

ran out of beads and could not make Pb samples
