now, any observant bee who chugs cola knows that coke and many other soft drinks have phosphoric acid in it. the main problem with such drinks and the extraction of the phos is the large load of other thick syrups, which would be hard to fully and confidently seperate.
in walks 'sweetened Nestea iced tea', a plastic bottled drink distributed by (you guessed it) coca cola. the ingredients as listed:
Water, High Fructose Corn Syrup and/or Sucrose, Tea (Natural Tea Essence and Natural Tea Concentrate from Tea Leaves), Natural Tea Flavors, Phosphoric Acid.
even if the phos is only 3-5 ml per 473 mL listed, that's a pretty good yield at 99 cents a bottle.
any ideas?
