Tasks for 17 September

  • To run UV-Vis measurements of MG left in solution (not absorbed by PVA polymer film).
  • To finish synthesis of 10 % PVA-exfoliated clay
  • To run pXRD

UV-Vis analysis of MG leftover solutions

  • Dilutions of some of the MG solutions were made in order to be able to use the spectrometer
    • Diluted 200 ppm 100 times by adding 100μL to a 10 mL volumetric flask. This was done for the polymer film-containing solutions.
  • Also diluted 80 ppm 50 times by adding 200μL to a 10 mL volumetric flask.
  • Diluted 200 ppm and 80 ppm MG 100 and 50 times respectively. Then ran UV Vis measurements to measure absorbance of MG green onto glass.
