Separation and purification chemistry Britannica
Separation and purification, in chemistry, separation of a substance into its components and the removal of impurities There are a large number of important applications in fields such as medicine and manufacturing Since ancient times, people have used methods of separating and purifying chemical14 SEPARATION TECHNIQUES 141 Introduction The methods for separating, collecting, and detecting radionuclides are similar to ordinary analytical procedures and employ many of the chemical and physical principles that apply to their nonradioactive isotopes However, some important aspects of the behavior of radionuclides are14 SEPARATION TECHNIQUESThe Separation process is used to transform a mixture of substances into distinct products Mixtures are the product of mechanical blending of chemical substances such as elements and compounds, without formation of any chemical bond or change in the individual components, so that each constituent can retain its original stateSeparating Mixtures Physical Separation Techniques
