Abstract:
Volatile phenols in the wastewater provide a basic parameter of the pollution. Spectrophotometric method based on the reactions of the individual phenols with 4-aminoantipyrine in the presence of an oxidizing agent is the current official analytical method in many countries. In this paper, we propose a method for extracting the resultant colored dye with ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate instead of chloroform. The results revealed excellent extraction efficiency, and the used ionic liquid could be regenerated easily. The method with small volume green reagent could be potentially applied in portable devices for in situ environmental analysis.
