Objective
- Start Analysis on pXRD spectra
- new PVA and 10% PVA-clay synthesis
- set up new experiments with PVA and PVA-clay films soaking in Arsenic (As) and Mercury (Hg) each with 150ppm, 100ppm, 50ppm

PVA-Clay Cation Exchange
- After centrifugation the clay was laid out on a watch glass and dried
- The dried clay was removed from glass and crushed using a mortar and pestle
- It was then transferred into a scintillation vial and massed 1.0484g of NaMT cation exchange powder
- The vial was placed into a oven in order to remove any excess hydrate
Data
XRD analysis of PVA film soaked in 80ppm Malachite Green
