Want this question answered?
Adsorptive chromatography is an analytical technique used for the chemical separation of mixtures and substances. The technique depends on the principle of selective adsorption (not to be confused with absorption), a type of adhesion.
The general Principle involved in tlc is similar to that of column chromatography i.e. adsorption chromatography. In the adsorption process, the solute competes with the solvent for the surface sites of the adsorbent. Depending on the distribution coefficients, the compounds are distributed on the surface of the adsorbent.
An adsorption site is a location on a surface where molecules or particles can adhere or bind due to attractive forces. It is where adsorption occurs, where a substance accumulates on the surface of another material. Adsorption sites are important in processes like catalysis, gas separation, and water treatment.
i think mechanism is that,,thin layer chromatography is basically separation of mixture,and sample might adsorb on silics surface.here is adsorption mechanism
gravity separation
gravity separation
Separation of powers
yes
i think the definition of chromatography is the showing of colors in a different color. In other words it is the separation of a mixture showing what colors are in that mixture. by the way, check out the question that asks how many popsicles are in the world. its really cool! well the answer is. :-)
Examples are:- Adsorption- Chromatography- Decantation- Solvent extraction- Distillation- Crystallization- Electrophoresis- Filtration- Precipitation- Ion exchanging
Bulk separation involves adsorption of a significant fraction (10% or more by weight) from a gas stream.Reference: R. T. Yang, Adsorbents: Fundamentals and Applications, John Wiley & Sons, Hoboken, 2003.
