1. To take up and hold by absorption.
2. To take up and hold by adsorption.
So what’s the difference between absorption and adsorption, besides a turned-around letter b? Absorption is when a substance is completely assimilated by another while in adsorption the substance deposits on the surface of another.
Back-formation from absorb, from Latin absorbere, from ab- (away) + sorbere (to suck). Earliest documented use: 1909.
“Nitrate is an anion and is not attracted to or sorbed by soil particles.”
