* For PVOH 22K glutaldehyde porphyrin films that were crosslinked, all films maintained a swirled light pink / salmon color appearance. | |||
* During crosslinking and excessive heating, the porphyrin films began to turn lime green; most films turned green upon entering the fixant solution composed of Na<sub>2<sub>SO</sub>4</sub> and H<sub>2</sub>SO</sub>4</sub>. | |||
* Most PVOH 22K glutaldehyde porphyrin films had some amount of porphyrin leach out into various solutions during crosslinking. For this reason, after every switch or movement of a porphyrin film to another solution, a small amount of each solution was collected for UV-Vis analysis. | |||

OBJECTIVES
New CuSO4 Dilution Standards for Atomic Absorption
(20 ppm CuSO4)V1 = (0.1 ppm CuSO4)(12mL) V1 = 0.6mL of 20 ppm CuSO4
(20 ppm CuSO4)V1 = (0.5 ppm CuSO4)(12mL) V1 = 1.2mL of 20 ppm CuSO4
(20 ppm CuSO4)V1 = (1 ppm CuSO4)(12mL) V1 = 3mL of 20 ppm CuSO4
(20 ppm CuSO4)V1 = (2 ppm CuSO4)(12mL) V1 = 6mL of 20 ppm CuSO4
(20 ppm CuSO4)V1 = (3 ppm CuSO4)(12mL) V1 = 9mL of 20 ppm CuSO4 Using the following concentrations(shown above), a calibration curve was prepared.
Atomic Absorption NaMT-CuSO4 Exchanged Filtrate Solutions
Fixant Solution Preparation
(Actual Na2SO4 Mass: 199.9953g)
Crosslinking Porphyrin FilmsFollow same protocol regarding crosslinking glutaldehyde films 9/21/12; however, pay attention to the two PVOH films that will not be placed in the fixant solution during the crosslinking procedure.
