October 24, 2014 Procedures Make Exchanged Clay Films THP Bromide Exchanged Clay: Add 7mL of water to ~1.0 g PVA and ~0.11 g of THPB exchanged NaMT in a glass vial Stir the solution with constant heating at 75C until the polymer is dissolved and the clay is dispersed (~15 minutes) Cool the solution to room temperature Add 0.5mL 0.8 wt% glutaraldehyde. Stir for an additional 3 minutes to ensure homogeneity Pour solution into a teflon dish to dry until the next class Choline Chloride Exchanged Clay: Add 7mL of water to ~1.0 g PVA and ~0.11 g of CC exchanged NaMT in a glass vial See above Column Preparation Glass wool placed in the bottom, saturated with methanol, drained ~3mL of sand added on top of the glass wool, saturated with methanol and then rinsed with water several times until liquid runs clear 10 g silica gel slurried in methanol gently poured into column, rinsed twice with water 10 mL BPA, let soak into the column 10 mL water run through column, collected in 5 mL increments 30 mL methanol run through column, collected in 5 mL increments Data
