Objective Start Bead Preparation Make 3% bentonite solution Description Make 100mL 3% bentonite solution. 97mL of water w/ 3g bentonite. Make 10% Beads Create a solution of PVOH, bentonite solution, water, and HCl. 1.25g PVOH, 5 mL bentonite solution, 15mL HCl, 35mL water Place this solution on a hot plate and heat at 70 degrees and stir at 240 until everything has dissolved (for 30 mins). Add 30 mL of this solution to a 100 mL solution of ethyl acetate in a dropwise manner stirring at 380 rpm. Add 1.5 mL of glutaraldehyde and stir at 260 rpm for 3 minutes. Add 1.5 mL of glutaraldehyde and stir at 260 rpm for 7 minutes. Make 25% Beads Same procedure as above with these amounts: 1.25g PVOH, 13 mL bentonite solution, 15mL HCl, 27mL water Data Add data and results here...
