Solvent Extraction - an overview | ScienceDirect Topics

Solvent extraction is often used to remove proteins and lipids from NAs. The pH values of the extractant organic phase and of the starting aqueous phase are very important because partition coefficients of NAs are pH-dependent. A classical system for solvent extraction uses a sequential extraction with phenol : chloroform (1 : 1).
