Under which circumstances is it wise to use a mixture Chegg.com
Activated carbon is added to a mixed solvent adsorb highmolecularweight impunities which are often colored and relatively less soluble. a b. A mixture of solvents is used when no single solvent has the desired property of rendering the substance soluble when hot and insoluble when cold. A mocture of solvents is used to crystalize very pure
Activated carbon Wikipedia
Uses. Activated carbon is used in methane and hydrogen storage air purifi ion solvent recovery decaffeination gold purifi ion metal extraction water purifi ion medicine sewage treatment air filters in respirators filters in compressed air teeth whitening production of hydrogen chloride and many other appli ions.
Basic arrangement of adsorptive solvent recovery with steam
The most common adsorbent is activated carbon in the shape of 3 or 4 mm pellets or as granular type with a particle size of 2 to 5 mm 4 x 10 mesh . A schematic flow sheet of a two adsorber system for the removal of waterinsoluble solvents is shown in Fig 22.1.4.

Regenerate activated carbon using organic solvents Journal
Adsorption by activated carbon is a mainstream technology for the removal of soluble chemicals from waters and wastewaters as well as for the removal of organics from vapor streams. Activated carbon basically acts like a sponge accumulating the chemical species removed from the liquid or vapor stream.

Is there a solvent that can dissolve amorphous carbon
Eventually you might want to try solvents with a better affinity to both amorphous and nanostructured carbon such as cyclic amides. In particular carbonbased materials show good solubility in N
solubility include polarity and the ability to hydrogen bond. For example a compound having just a few carbons and an alcohol functional group FG would be expected to be soluble in solvents that have a few carbons and an alcohol FG or in some other polar solvent and to be less soluble in nonpolar solvents.
Why activated carbon dissolved in my sample
Activated carbon as you mentioned is insoluble in water and organic solvents and all usual solvents. What happened in your experiment is that some of the activated carbon molecules made a colloid
