adsorption
The property of a solid substance to attract and hold to its surface a gas, liquid, or a substance in solution or in suspension. For example, condensation of a gas onto a surface. Cf.:absorption. [L. ad, to, + sorbeo, to suck up]
- immune a. 1. removal of antibody (agglutinin or precipitin) from antiserum by use of specific antigen; after aggregation has occurred, the antigen-antibody complex is separated either by centrifugation or by filtration; 2. removal of antigen by specific antiserum in a similar manner.

ad·sorp·tion (ad-sorpґshən) [L. ad- to + sorption] the attachment of one substance to the surface of another; the concentration of a gas or a substance in solution in a liquid on a surface in contact with the gas or liquid, resulting in a relatively high concentration of the gas or solution at the surface. Cf. absorption.
