I got the idea from using filters and other filtration systems in previous research experiences, and also how recently... someone gave me a bunch of Monster Energy drinks but they aren't sugar free so it got me thinking how it would be possible to extract the sugar from the Energy Drinks mechanically.
Sugar molecules are 1nm in size
salt (NaCl) is .06nm in size and water molecules are .275nm in size.
Would this work as planned or is there something my reasoning has a huge gap in? :)
Theoretically, yes, but it would take a fair amount of time and energy for each can, or a very large filter. A one micron filter needs a fair amount of vacuum to filter solids out of water. To remove sugar molecules, you're starting to get into the realm of reverse osmosis instead of nanofiltration.
You might not filter out all the sucrose, either, since the molecule measures approximately 1.1 x 0.9 x 0.8 nm, and you probably wouldn't filter out any glucose, citric acid, or caffeine.
It would be easiest to just drink black coffee instead, but if you just want to see if it can be done, go for it!
Molecular size isn't the only consideration. Others include charge effects, aggregation of molecules, and hydration.
Not possible it is in dissolved state. You need to use evaporative crystallizer
