OBJECTIVES
Preparations For Cu2+ Film Exchanged Solutions & Vacuum Filtration ProceduresFollow procedural protocol for Cu2+ film exchanged solutions & vacuum filtration procedures 10/05/12; however, instead of using clay, use 1.0g films prepared containing PVOH, glutaldehyde, and clay samples. In addition, only exchange films for solely 10min time interval.
UV - Vis Procedures
UV-Vis of Porphyrin Solutions
* Wavelength range = 200 - 800nm * Slit width = 1.0nm UV-Vis Analysis Notes
Porphyrin Film PreparationsFollow procedural protocol for preparing glutaldehyde films 9/25/12; however, add ~ 1mL of porphyrin in addition to glutaldehyde for each film before pouring substance into a Teflon dish.
