Objective

Part I

  • Finish AA/ISE conductivity
  • UV-Vis Cu+2 absorption solution
  • Cu+2 absorption using about 1g film(PVOH, PVOH+NaMT, PVOH, OM-MT).
  • UV-Vis calibration curve for porphrin solutions (determine the maximum abs).
  • Remake fims, if necessary.

Part II

Cross Link Porphyrin Films.

Description

  • Cross-Link Porphyrin Films.

(a) measure the exact amount of H2SO4 solution used. (b) save 2-5 mls of H2SO4 stock solution in vial (C) save 2-5 ml of H2SO4 used to cross-link the solution (if colored). (d) measure the exact amount of HCl solution used. (e) save anbout 2-5 mls after reaction (in case if the solution is colored). (f) 2% HCl solution in a 100 ml beaker- that implies 2 ml HCl and 98 ml of millpore water (as directed in NASA tech paper).

  • CuSO4 standard solutions were re-made: 20 ppm, 5ppm, 2.5 ppm, and 1.5 ppm
  • UV-Vis spectra of CuSO4 filtrate solutions (for 1min, 5min and 10 mins) were taken.
  • Cross-linking of porphyrin films with 1ml of glutaraldehyde (0.5 g PVOH via NASA tech paper) was prepared.
