Charcoal, active, adsorption surfactants

Derivation of the Gibbs adsorption isotherm. Determination of the adsorption of surfactants at liquid interfaces. Laboratory project to determine the surface area of the common adsorbent, powdered activated charcoal. 

Studies of adsorption of nonaromatic organic compounds are not as abundant but they are very diverse (and are cited here only to illu.strate and emphasize this diversity). They go back to the interwar period (see, for example, Refs. 571-573, when activated charcoal was being developed for chemical and biological defen.se and its properties were intensely studied [2,3]). More recently, the removal of trihalomethanes [574-579], amines [580,581], acetic acid [582, the pesticide thiram [583], chlorinated organic compounds [584,552,585,586,403, 587-591], alcohols [572,592,593-597], carboxylic and fatty acids [592,483, 598,594,599], N-acetylcysteine [600], amino acids [601], benzo-15-crown-5 ether [602], quaternary ammonium compounds [603], organophosphates and or-ganophosphonates [604] has been studied. Adsorption of surfactants has also been of continued interest [605-614,143,6l5-617. ...
