Objective Make 40% clay beads Start gather adsorption data for malachite green in Activated Carbon column and 10% clay beads column. Description 40% clay beads: 1.25g PVA 1.25g PVA/6*4 = 0.833333g 0.833333g Bentonite * 97ml solution/3g bentonite = 27 mL bentonite solution 55mL solution - 27 mL bentonite solution - 15mL HCL: 13 mL H2O Create a solution of 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 30 mL solution of ethyl acetate dropwise stirring at 380 rpm Wait 3 mins and 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. Find Adsorption Data for MG in Activated Carbon and 10% beads Add 50ppm into columns 5mL of a time. Collect effluent into vials. Continue adding MG until the effluent has about the same concentration as the MG run through the column Once effluent appears the same color going in a coming out, start adding water 5mL at a time and collect effluent. Finish effluent collection when water runs clear again Data Drop Rate Activated Carbon: 12 drops/min Drop Rate 10% Carbon: 20 drops/min
