The sources being moved are all much too narrow, and / or are commercial, lacking page nos. and relevant dates, or are outdated, etc. They are therefore inadequate / inappropriate for a general introductory chemistry article. Moreover, they are not at all indicative of the enormous secondary literature available on this subject, and are only of value as a peripheral sources (i.e., sources of examples of application). Hence, the current three narrow and flawed references are being removed here, to Talk. This is being done as a respectful option to their simply being deleted. A multiple issue/citation tag is being added for the interim, until the article can be moved into reasonable shape. Inadequate/inappropriate sources appearing in the earlier version of the article (leading < removed):

How is this topic distinct from Separation process? If there is no difference, should this be merged into the other? -Bryanrutherford0 (talk) 19:12, 17 February 2015 (UTC)[reply]

This article is a fundamental concept in chemistry and as such should be expanded upon. AmerHanan (talk) 21:08, 26 February 2018 (UTC)[reply]

Add: In liquid-liquid extraction compounds separate on their relative solubility in two different immiscible liquid phases. This technique has been applied in several fields such as analytical chemistry and biology. ^[1]
