I dunno...reverse osmosis???
------
The separation is possible with activated charcoal; the solution is then evaporated to obtain crystallized caffeine.

How do you separate mercury from caffeine?
add vinegar
Does caffeine evaporate faster than water?
Caffeine is a solid, caffeine doesn't evaporate; water, of course, can be evaporated.
Can the separating funnel separate mercury and caffeine?
I do not think so!
Would ethanol be a good solvent for extracting caffeine from water?
No, water and ethanol are miscible in one another. This means they would not separate into two distinct layers when mixed. You would need a less polar solvent such as methylene chloride or ethyl acetate to achieve two layers and properly extract caffeine from water.
How do you separate caffeine on soft drinks?
Its much easier to simply buy caffeine-free drinks to begin with.But, if you already have caffeinated drinks and wish to separate the caffeine, it can be done pretty easily.If you are trying to isolate the caffeine from the drinks, you can perform an organic chemistry "Base / Acid, Liquid-Liquid extraction."In a nutshell, it would go like:1-Iincrease the pH of the soft drink to 11 or 12 (check for caffeine specifically)2- Add a non-polar solvent and mix thoroughly for several minutes3- Let the mixture sit for several minutes/hours, it should form two layersUsually the bottom layer will be the "water" layer, while the upper layer will be the non-polar solvent containing your caffeine. Some non-polar solvents are heavier than water (like chloroform), and will form the bottom layer.4- Separate the two layers, keep your non-polar layer with the caffeine.5- Add a dilute strong acid like hydrochloric acid--or even vinegar (acetic acid), to the non-polar layer and shake for several minutes.6- Let the mixtures stand for several minutes until two layers form again.7- The caffeine will now be in your aqueous layer (the water layer). Again, this is typically the lower layer. Separate the layers, keep the water layer.From here, you can do several things, you could:A) Let the water evaporate, and it should leave caffeine as a goo or crystal substance at the bottomB) You could again increase the pH in the water layer to 10 or 11. Let sit in your fridge and caffeine base should precipitate (fall out of solution).
What has the least caffeine?
Clean water.
Is there a list of Diet drinks without caffeine?
Good old liquid water. There is Caffeine Free Pepsi and Caffeine Free Coke.
Why did the caffeine leave the water and move into the dichloromethane?
Dichloromethane is a water-immiscible solvent that works well, because caffeine is highly soluble in it
Why are sources with caffeine not a good source of water?
that's because caffeine causes you to lose more water than normal in your urine.
Why is coffee without caffeine called decaf but coke without caffeine is called caffeine free coke not decaf coke?
Coffee beans are naturally caffeinated so the existed caffeine must be removed, i.e. de-caffeinated. Cola (Coke, etc) often has caffeine added as a separate ingredient, so if that ingredient is skipped, the cola is free of caffeine.
Do water drinks contain caffeine?
obviously not...
What was can you separate sugar from water?
You can separate sugar from water by evaporation of the water.
