Nov 7 - Class Paper Objective Review X-Ray data Synthesize beads Review Class Paper information Notes Michael continued to represent AMT with bead synthesis. The following are notes fromhis notebook Synthesize beads with Mary and Melvin. Description Stir 30 mL of ethyl acetate + 500 uL of glutaraldehyde Add your PVA-clay (approximately .5 g of PVA and .0575 g NaMT) in a dropwise manner. Immediately start timing the reaction for 2 minutes when you do the first drop. After 2 minutes, slowly add 7 mL of 0.2 M NaHCO3. Once completed, transfer to a falcon tube and centrifuge for 1 minute at 3000 rpm, rotor 41. When beads are separated from the organic phase, pipet out the organic phase and re-suspend the beads in distilled water. Protocol adopted from Mary. X-Ray XRD results were saved using the following instructions PDXL- click OK Load data Export Use first two columns to graph In the graphs the 1st peak would be any sodium, 2nd peak Tape and PVA, 3rd Peak Pan Class Paper Measurements mg analyte/mass polymer Kinetics Beads, PVA, PVA with clay Films Other Absorbents like activated carbon and zeolite (this makes the experiments relevant) Accurately stocks always the same across the groups, measure each day and use calibration curves averages Mass dehydrate the sample Other measurements SEM BET Bead size DSC XRAY
