How adsorbe a substance in a powder (fine) ?
Hi, what is some methods to adsorbe a substance (molecule or microbs) in a fine powder (eg resin, talcum, chalk, salt, pepper, plastic polimers,
elastomers, cacao) ?

Before you tackle adsorption, I suggest another project: 'what is the best way to pose a question so that someone might provide me with useful answers
or information?'. In the present case, your question is hopelessly overbroad, akin to asking 'how do I distill?'; the only answer someone could
provide to such a question might be a link to some weighty compendium of knowledge on the subject. If you have something specific that you want to
adsorb, then we would like to know
- what it is
- why you are trying to adsorb it
- what candidate materials you would prefer or have access to

Absorption of what into what?
Also, any given item dissolved or absorbed into another would require different reagents.
“If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found
the object of his search.
I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.”

Usually this is done by dissolving the compound you want to adsorb into a suitable solvent, adding the adsorbent (powder) to that mixture and
evaporating the solvent to dryness with a rotavap.

Odd way of using the word adsorb. As I recall, adsorbsion is a surface phenomena.
A type of affinity or light molecular bonding between two differing molecules. One of which might be either a solid catalyst or a chromatographic
media, and the other being either a chemical undergoing a catalyzed reaction like a hydrogenation, or a chemical being purified or refined, as by
elution through a column of adsorbent material, as in column chromatography.
I'll check my definitions somewhere.
