===Measurement of MG absorbance by activated carbon=== | |||
* To add 10 mL of 23.3 ppm MG dye to previously prepared scintillation vials containing approximately 0.01 g of activated carbon. | |||
* As soon as you add the MG dye start the timer, and stir homogeneously. | |||
* Stop timer 2 seconds after starting filtration (which takes 4 s in total) | |||
* Take UV-Vis measurements of the filtrate in the range 200-400 nm. | |||
