The extent of the separation can be expressed in terms of one factor called Seperation Factor \beta . This is related to the distribution ratio of A and B. \boxed { \beta = \frac { D_{ A } }{ { D }_{ B } } = \frac { \sfrac { { C }_{ o(A) } }{ { C }_{ a(A) } } }{ \sfrac { { C }_{ o(B) } }{ { C }_{ a(B) } } } } It is ratio therefore no unit and no dimension. The larger value is always placed in the numerator. \beta must be made as large as possible by choice of extractant and by adjusting the volume ratio. When D_{ A } = 10 and D_{ B } = 0.1. The \beta = \frac { 10 }{ 0.1 } = 100% single extraction in case will remove 91% of A and 9% of B. It can be obtained for A, E = \left[ \frac { 100{ D }_{ A } }{ { D }_{ A } + \sfrac { { V }_{ W } }{ { V }_{ o } } } \right] for { V }_{ W } = { V }_{ o } \therefore \sfrac { { V }_{ W } }{ { V }_{ o } } = 1 \therefore E = \left[ \frac { 100 \times 10 }{ 10 + 1 } \right] = \left[ \frac { 1000 }{ 11 } \right] = 90.9% Similarly for B, E = \left[ \frac { 100{ D }_{ B } }{ { D }_{ B } + \sfrac { { V }_{ W } }{ { V }_{ o } } } \right] for { V }_{ W } = { V }_{ o } \therefore \sfrac { { V }_{ W } }{ { V }_{ o } } = 1 \therefore E = \left[ \frac { 100 \times 0.1 }{ 0.1 + 1 } \right] = \left[ \frac { 10 }{ 1.1 } \right] = 9.1% The seperation of A is almost complete from B if the seperation factor B is high. It can be only in the case when { D }_{ A } is large and { D }_{ B } is small. For a given value of { D }_{ A } and { D }_{ B }, the seperation effect can be increased by adjusting the volume ratio given by Nush Densen Equation which says. \boxed { \frac { { V }_{ o } }{ { V }_{ W } } = \frac { 1 }{ { \left( { D }_{ A }{ D }_{ B } \right) }^{ \sfrac { 1 }{ 2 } } } } #SolventExtraction #AnalyticalChemistry #Extraction # Analytical Reasoning https://www.youtube.com/watch?v=X-7CQplERYM&list;=PL9AUXQTZw3SsoaOllWEuB7ahBesJQTLpE English Grammar https://www.youtube.com/watch?v=GmPy-ct2rJ4&list;=PL9AUXQTZw3SsCmUjRKccku7xy9u8o3fc9 Interview Skills https://www.youtube.com/watch?v=Pa_pdAQRZNQ&list;=PL9AUXQTZw3SvF80iquuqAhtbX1hTfyqfH Managerial Economics https://www.youtube.com/watch?v=U7uDmEe9Bn4&list;=PL9AUXQTZw3SsVHepwS2e7W2kjxzlKKjEb Royalty Free Stock Footage https://www.youtube.com/watch?v=a1xbYDCDGgI&list;=PL9AUXQTZw3SvWSpm0MpIPheeTlg4yUx7m Chemical Thermodynamics - Physical Chemistry https://www.youtube.com/watch?v=cATdLP86uHQ&list;=PL9AUXQTZw3SsLGGp8p6xeGwM3P9adIRR1 Ionic Equilibria - Physical Chemistry https://www.youtube.com/watch?v=llTs2-BMmgA&list;=PL9AUXQTZw3SuWLAc0-MNpD8Vc-7LyN52w Electrochemistry - Physical Chemistry https://www.youtube.com/watch?v=ifdy9wnF80s&list;=PL9AUXQTZw3Sssn-kip7xzKGzwljSRPEX2 Solid State - Physical Chemistry https://www.youtube.com/watch?v=Pz-yaCYkHZI&list;=PL9AUXQTZw3SuoPwu8UFZq4zXiPEC-So6i Gaseous State - Physical Chemistry https://www.youtube.com/watch?v=bvp0d8qZCpE&list;=PL9AUXQTZw3Ssp6Ne6_XbBu8TLuO7qEd4L Colloidal States - Physical Chemistry https://www.youtube.com/watch?v=yjeFUF-fNLQ&list;=PL9AUXQTZw3SszL0qFEw1jciS3QIXZB4aZ Stereochemistry - Organic Chemistry https://www.youtube.com/watch?v=N5GU6379LCo&list;=PL9AUXQTZw3Su_8A-izFKGfBJvSZY7XcCx Nanomaterials - Engineering Chemistry https://www.youtube.com/watch?v=eDVwEf2PgRI&list;=PL9AUXQTZw3SsYzEUlxhIzmVCvRcyCy9fh Water and Its Treatment - Engineering Chemistry https://www.youtube.com/watch?v=eOsZ12nuJnA&list;=PL9AUXQTZw3Ss8p3l-b_YIkD-8ZvX4YDsy Electrochemistry - Engineering Chemistry https://www.youtube.com/watch?v=oleTF2Qw-gg&list;=PL9AUXQTZw3SuETg2vcx6uEYKFwBVJtEot Environmental Studies https://www.youtube.com/watch?v=-jm3JOcUwdQ&list;=PL9AUXQTZw3SvK27T5RCYJoP_NpndyuEs2 Optics - Applied Physics https://www.youtube.com/watch?v=XUw7C4AE0Hk&list;=PL9AUXQTZw3StU-aX5h47EZTEkOteCjdz6 For Details Visit http://cepekmedia.co.nf http://cepek.hol.es/ http://edmerls.66Ghz.com/ http://edmerls.tk/
