Gas solubility ...
is independent of temperature and salinity
With the diffusion of a dissolved substance in sediment pore waters, and the dissolved substance chemically react as a educt, then a
negative deviation of a linear steady state flux is observed
What is adsorption?
accumulation of substances at the interface between two bulk phases
How is surface excess defined?
The difference of the total concentrations of a substance in a system considering the real interface and the modelled interface
What is the Gibbs convention?
Placing the dividing surface at a position that the surface excess of the major component becomes zero
What is the most prominent feature of surfactants?
have hydrophobic and a hydrophilic groups
When do surfactant form micelles?
If no space is left for surfactant molecules to adsorb at the gas-liquid interface
Micelles are ...
Micelles are well structured aggregates of surfactants with hydrophic tail oriented inwards and hydrophilic group positioned at the micelles out surface.
Foam is typically instable because...
water drains away from the bilayer and elektrostatical repulsion of surfactants with the thinning of the aqueous layer between surfactant films
Foam forms...
after wave breaking (short-lived)
Aerosols with potentially surface-active compounds as main component are primarily formed
in the presence of biological activity
What are examples of adsorption in the marine environment?
Adsorption of surfactants at the air-water interface
