Separointimenetelmät

Separointimenetelmät, or separation methods, encompass a broad range of techniques used to physically divide a mixture into its constituent components. These methods exploit differences in the physical or chemical properties of the substances within the mixture, such as boiling point, solubility, density, particle size, or affinity for a particular substance. The goal of separation is to isolate one or more desired components in a purer form or to remove unwanted impurities.

Common separation methods include distillation, which separates liquids based on their differing boiling points. Filtration is employed to separate solid particles from a liquid or gas by passing the mixture through a porous medium. Centrifugation utilizes centrifugal force to separate components of different densities, often used for separating solids from liquids or immiscible liquids. Evaporation is used to separate a soluble solid from a solvent by vaporizing the solvent. Chromatography encompasses a family of techniques that separate compounds based on their differential partitioning between a stationary phase and a mobile phase. Extraction involves selectively dissolving one or more components of a mixture into a solvent. Crystallization is a process where a solid forms from a solution, melt, or more rarely deposited directly from a gas. The choice of separation method depends heavily on the specific mixture, the desired purity of the separated components, and the scale of the operation, ranging from laboratory-scale experiments to industrial processes.
