What are the steps to making solvent extraction?

Answer 1

The following steps to be taken in solvent extraction 1.Take out the sample, filtrate it and measure the density. Analysis to be done for the metal/component which is to be extracted. If more components are presented then analysis to be done for all components 2.Select the solvent which is suitable for the sample 3.Prepare solvent with diluents or modifiers 4.Measure the solvent density 5.Both solvent and sample densityies should not be same 6.Take measured quantity of sample and solvents in a separating funnel 7.Shake it 5-10 minutes or until equilibrium achieved 8.After equilibrium achieved separate the organic and aquous layers in to separate beakers 9.Analysis to be done for the metal/component which is to be extracted. If more components are presented then analysis to be done for all components 10.This analysis to be done in raffinate. 11.In extract layer do the stripping and and separate the solvent. 12.Mutual solubilito be calculated in extract and raffinate layers 13.The analysis described above is to be followed for stripped solution also. 14.The stripped organic to be analyzed and re use it. 15.Calculate the loading capacity of organic 16.Calculate the selectivity 17.Using date draw the equilibrium diagram 18.Calculate the stages required using Mc Cabe diagram
