Methods of seperation

Filteration - used for seperation the soild or suspention of liquid.

Filtration is a mechanical or physical operation which is used for the seperation of soilds from fluids by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained, but the seperation is not complete: solids will be contaminated with some fluid and filtrate contain perticles.

Evaporation - used of obain the solid from a solution.

Evaporation is a type of vaporization of a liquid, that occur only the surface of a liquid. Teh other type of avporization is boiling, that instead occurs on the entire mass of the liquid. Evaporation is also part of the water cycle.

Chromatography - used to seperate out one colour from a mixture of colours.

Chromatography is the collective term for a set of laboratory techniques for the seperation of mixtures. It involves passing a mixture dissolved in a mobile phase through a stationaty phase, which seperates the analyte to b emeasured from other molecules in the mixture based on diffrent partitioning between the mobile and stationary phases. Subtle diffrences in compounds partition coefficient results in diffrent on the statinary phase and thus changing the seperation.

simple distillation - used to obtain the solvent from a solution.



Distillation is a method of seperation mixture based on diffrences on their volatilities in a boiling luquid mixture. Distillation is a unit operation, or a physical seperation process, and not a chemical reaction.

Fractional distillation - used to seperate one liuquid from a mixture of diffrents liuquids that have diffrent boiling points.



fractional distillation is the separation if a mixture into its component parts, or fractions, such as in seperating chemical compounds by their boiling point by heating them to a temperature at which several fractions of the compund will evaporate. It is a special type of distillation. Generally the component parts boil at less than 25°C from each other under a pressure of one atomosphere. if the diffrence in boiling points is greater than 25 °C, a simple distillation is used.
