difference between paper chromatography and absorption chromatography
Answers
Adsorption chromatography:
it is defined as a type of chromatography where the solute molecules are directly bound to the surface of the stationary phase.
In simple terms, adsorption chromatography could be explained as a gas or liquid that is adsorbed to a surface of a solid. Stationary phases possess a variety of adsorption sites.
Adsorption chromatography uses mobile phase in liquid or gas state and stationary phase in the solid state.
Adsorption chromatography is a liquid-solid extraction.
Paper chromatography:
it is an analytical method used to separate colored chemicals or substances. It is primarily used as a teaching tool, having been replaced by other chromatography methods, such as thin-layer chromatography.
In paper chromatography, the stationary phase is a special quality paper called chromatography paper.
Mobile phase is a solvent or a mixture of solvents.
Paper chromatography is a liquid-liquid extraction.
Answer :
Paper Chromatography
- Moisture functions as a stationary phase in the cellulose layers of the filter paper.
- The mobile phase is an organic solvent or a buffer.
- In the stationary phase, the more soluble compound will travel slower.
Absorption Chromatography
- The stationary phase is made up of solid material.
- As a mobile phase, liquid is used.
- The elements travel in accordance with their respective affinity.
