Adsorber o absorber ::::: To adsorb or to absorb
Reading a book, it's common to find words which we assume that are synonyms. That's not the case for "adsorb and absorb", they are similar but not equal.
Adsorb refers to an two-dimensional action, because it means to retain something on the surface, for example:
"Heavy metals are adsorbed by the cell", because they're on the surface, on the cell wall.
Absorb refers to an three-dimensional action because it means to get inside something that was out before, for example:
"Heavy metals are absorbed by the cell", because they are inside the cell, they were trapped in the cell.
