Objective To run a timed experiment using zeolite Synthesize beads Notes Michael represented AMT for the synthesize of beads the following are his notes Create a bead synthesis process that produces larger quantities of polymer/clay beads. Beads Create a solution of 2.5 g PVA, 0.275 g NaMT, and 30 mL 10% HCl. Place this solution on a hot plate and heat/stir until everything has dissolved. Add 10 mL of this solution to a 50 mL solution of ethyl acetate stirring at 240 rpm in a dropwise manner. Add 1 mL of glutaraldehyde and stir at 260 rpm for 3 minutes. After 3 minutes, add 1 mL of glutaraldehyde and stir at 300 rpm for 2 minutes. After 7 minutes, add 7 mL of sodium bicarbonate and stir for 30 seconds. Remove the solution, put it into 2 50 mL Falcon tubes. Centrifuge the solutions for 1 minute at 3000 rpm. Pipette all of the liquid out of the tubes and replace with deionized water. Zeolite Andrew and myself worked on the zeolite experiment Dr. Hartings previously weighed out ~10mg of zeolite for the class. The table below list the weights of zeolite used for each time period. The concentrations of MG absorbed were calculated in the below image
