Objective 30% clay beads prepared Weighed columns activated Carbon 10% 20% 30% Description Data for the columns prepared for MG adsorption next time. Columns were filled approximately halfway with beads. 30% clay beads: 1.2505g PVA 1.25g PVA/7 * 3 = 0.0.5357g 0.5357g Bentonite * 97ml solution/3g bentonite = 17 mL bentonite solution 55mL solution - 10 mL bentonite solution - 15mL HCL: 23 mL H2O Create a solution of with PVA, bentonite solution and water Place this solution on a hot plate and heat/stir until everything has dissolved. Add 5 mL of this solution to a 50 mL solution of ethyl acetate dropwise stirring at 380 rpm. Add 0.5 mL of glutaraldehyde and stir at 400 rpm. After 7 minutes, add 7 mL of sodium bicarbonate and stir for 30 seconds.
