Separation vs. Purification: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on December 29, 2023
Separation is the process of distinguishing and dividing different substances or components, while purification is the process of removing impurities or unwanted elements from a substance.

Key Differences

Separation involves dividing a mixture into its individual components without changing their identities. Purification, in contrast, focuses on removing impurities from a substance to improve its quality or purity.

In separation, the goal is to isolate components from a mixture, like separating sand from water. Purification aims to make a substance pure, such as purifying water to make it drinkable.

Separation techniques can be physical, like filtration or sedimentation, and don't necessarily remove all impurities. Purification often involves chemical processes, ensuring the substance is free from contamination.
