What are the processes in separating mixtures?
Answer:
Physical and Chemical.
Adsorption
Centrifugation and Cyclones - density differences
Chromatography involves the separation of different dissolved substances as they travel through a material. The dissolved substances are separated based on their interaction with the stationary phase.
Crystallization
Decantation
Distillation - used for mixtures of liquids with different boiling points, or for a solid dissolved in a liquid.
Dryingby less butyou - removing liquid from a solid by vaporising it
Electrophoresis Organic molecules, such as protein are placed in a gel. A voltage is applied and the molecules move through the gel because they are charged. The gel restricts the motion so that different proteins will make different amounts of progress in any given time.
Elutriation
Evaporation
Extraction
Leaching
Liquid-liquid extraction
Solid phase extraction
Flocculation - density differences utilization a flocculant such as soap or detergent
flotation process - suspended solids are encouraged to float to the top of the fluid by rising air bubbles.
Fractional freezing
Filtration. Mesh, bag and paper filters are used to remove large particulates suspended in fluids, eg. fly ash, while membrane processes including microfiltration, ultrafiltration, nanofiltration, reverse osmosis, dialysis (biochemistry) utilising synthetic membranes can separate micrometre-sized or smaller species.
Precipitation
Recrystallization
Sedimentation - density differences
Gravity separation
Sieving
stripping
Sublimation
Winnowing
