Adsorption is a phenomenon in which molecules or ions from a fluid phase (gas or liquid) are attracted and retained on the surface of a solid phase (adsorbent). Adsorption is different from absorption ...

A procedure for combined sequential affinity adsorption-electrophoresis has been devised. Its use for the rapid purification of a calcium-dependent cyclic nucleotide phosphodiesterase from bovine ...

A membrane-adsorption technique for counting surface slick microbial populations was evaluated. The simple procedure gave bacterial and fungal populations several orders of magnitude greater than ...
