Analytical applications of crown ethers: III. Extraction and determination of nitrophenol isomers

Extraction of nitrophenols from water samples into benzene has been studied. The extraction is quantitative in the presence of crown ether when the pH of the aqueous phase is in the range 4.7 to 5.7. Beer's law is valid and a spectrophotometric determination of the nitrophenols is proposed.
