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. Data Add data and results here...
