Objective Bead Synthesis UV-Vis of Activated Carbon Description Weigh out 0.1000g of Activated Carbon into vials. BEM and MJ are doing 5 minute increments AMT and MA are doing 5+3 minute increments First five minutes are in single increments because Activated Carbon works quickly Stock solution created by James and Eleni for class (20ppm) 10mL of stock will be added to each vial UV-Vis is taken at specific time At the exact moment, the solution is removed from the vial into epi tubes to stop reaction with malachite green solution Data Masses of Activated Carbon Minutes Mass of Activated Carbon (g) 0 0.0996 1 0.099 2 0.0999 3 0.0092 4 0.104 5 0.1008 10 0.1062 15 0.0999 20 0.0995 25 0.1006 30 0.105 35 0.1013 40 0.1017 45 0.101 50 0.1 55 0.1013 60 0.1003 It was seen that too much Malachite Green was absorbed with 0.1000g of Activated Carbon, therefore the same procedure will be done with solely 0.0100g of Activated Carbon New Masses of Activated Carbon Time Mass of Activated Carbon (g) 15s 0.0096 30s 0.0098 45s 0.0104 1min 0.0116 1min + 15s 0.0096 1min + 30s 0.0107 1min + 45s 0.0094 2min 0.0125 3min 0.0105 3min + 30s 0.0118 4min 0.0095 4min + 30s 0.009 5min 0.0117 6min 0.0094 7min 0.0153 8min 0.0093 9min 0.0131 10min 0.0095 Notes This area is for any observations or conclusions that you would like to note. Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
