Objectives
*NaSO4 solutions were prepared 2012/9/21 CrosslinkingNote: Films crosslinked on 10/03/2012 still remained intact in deionized H2O despite using too little glutaraldehyde.
Note: All GA films were cut in half prior to crosslinking. Remaining uncrosslinked glutaraldehyde films remained under the fume hood
Atomic AbsorptionGeneral Protocol for use of AA-6200 Shimadzu:
AA results from CuSO4 solutionsGold nano particles were clogging the sample collection tube. All results were invalid. The data will be recollected on the next date
