the process of -
(a) sorption (b) desorption (c) adsorption​

Answer 1

Answer:

Explanation: adsorption

Answer 2

Adsorption is the process by which molecules of a substance from a gas mixture or liquid solution became attached to a solid or liquid surface

Explanation:

Adsorption is originated by the surface forces acting on the solid-gas, solid-liquid, gas-liquid, or (in the case of immiscible liquids in contact) the liquid-liquid interface.

• In adsorption from solutions, the behavior depends greatly on whether the solutions are of nonelectrolytes or electrolytes.
• Adsorption from nonelectrolyte solutions depends on adsorbate concentration and, in the case of dilute solutions, is similar to gas adsorption.
• The solvent properties manifest themselves at high concentrations.

Example:

• The adsorption performance and mechanism of mixed dye system with  modified sepiolite since the kinetics and thermodynamics of two-component and three-component  the solution was much more complicated.
• In the  two-component and three-component mixed solution, the removal effciency of each dye was basically  as same as that of a single dye system.
• The decolorization effciency of the single component dye in  the multi-component system was lower than that of the single dye system.
