Factors Affecting The Solvent Extraction Technique (1)

1
Solvent Extraction

• Extraction involving two immiscible liquid for
  separation of metal

2

• Solvent Extraction technique ensure industrial
  purification, extraction and recovery of metals
  in the such as uranium, copper, nickel, cobalt
  and rare earths, from solutions.
• It utilizes a special reagent as a solvent to
  ensure the transfer of metal (to be extracted )
  from one liquid media to the another liquid
  media.
• The two liquid phases used in the extraction
  process are immiscible that ensure the formation
  of two separate phases.

Factors Affecting The Solvent Extraction Technique

• Composition of feed solution
• Nature if the metal required to be extracted
• The feed solution should not be miscible with
  another liquid phase so that the extraction of
  the metal can take place with effective measures.
  And the metal desired to be extracted for the
  solution should not be miscible with the two
  liquid phase used in et extraction process.

• The solvent extraction technique is commonly
  employed in the petroleum refining industry. It
  is specifically used in the extraction of
  automobile lubricating oil,  aromatic hydrocarbons
  ,  paraffinic and naphthenic hydrocarbons
• The broad area of application where solvent
  extraction technique is used widely include
  hydrometallurgy, rare metal recycling, bio
  separation, and environmental improvement.
• Another important application of solvent
  extraction technique include Sweetening of
  gasoline by extraction of sulfur-containing compou
  nds separation of vegetable 
• oils into relatively saturated and unsaturated
   glyceride 
• esters recovery of valuable chemicals in by-p
  roduct coke oven plants pharmaceutical refining p
  rocesses and purifying of uranium.

• The usage of solvent extraction technique in
  chemical laboratories has been proven in various
  aspects. It is commonly used in the during the
  purification of the  organic synthesis and in
  analytical separation of the mixtures in order to
  remove one or more constituents.
