SEPARATION TECHNIQUES - INTRODUCTION
SEPARATION TECHNIQUES -INTRODUCTIONSIVASWAROOP OF SEPARATION TECHNIQUES :TO IDENTIFY WHAT TO BE SEPARATED FROM OBTAIN IMPORTANT AND PURE REMOVE UNWANTED PARTICLES. TYPES OF SEPARATION TECHNIQUES : SEPARATION TECHNIQUES are classified based on type of mixtures: SEPARATION techniquesFor solid in liquid mixturesHomogenous:1. Evaporation 2. distillation 3. centrifugationHeterogenous:1. Sedimentation / gravitation 2. Filtration 3. Magnetic separation4. fractional distillationFor liquid in liquid mixturesHomogenous:1. Simple or fractional distillation . 2. Chromatography Heterogenous:1. Partition SEPARATION using funnel MAGNETIC ,soitusefulonlyforcertainsubstancessucha sferromagnetic(materialsstronglyaffected bymagneticfields)andparamagnetic(materia lsthatarelessaffected,buttheeffectisstil lnoticeable).
Fractional: Fractional distillation is used for the separation of a mixture of two or more miscible liquids for which the difference in boiling points is less than 25K. The apparatus for fractional distillation is like that of simple distillation, except that a fractionating column is fitted in between the distillation flask and the condenser.
