Frothing in chemistry
WebThe stabilization of a foam is caused by van der Waals forces between the molecules in the foam, electrical double layers created by dipolar surfactants, and the Marangoni effect, which acts as a restoring force to the lamellae. The Marangoni effect depends on the liquid that is foaming being impure. Webof additional water (1-2 mL) along with a small portion of activated charcoal.

Today’s rapid froth flotation processes rely on alcohol- and polyglycol-based chemistries.
WebAbstract. Foams and froths are of considerable practical importance not only in froth flotation of minerals or in adsorptive bubble-separation techniques applied to water purification but also in the food industry. Protein-stabilized foams have to be carefully controlled in the boiling and the fermentation stages of food preparation.
