Abstract

The use of a silver solid amalgam working electrode for HPLC with electrochemical detection has been investigated. The thin-layer and wall-jet detectors based on this electrode were constructed and applied for the determination of a mixture of nitrophenols. The optimal separation and detection conditions for the determination of 2-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol and 2-methoxy-5-nitrophenol in mixture were found using RP-HPLC at Nova-Pack C18 column and amperometric detection with the above mentioned detectors. It has been proved that the silver solid amalgam electrode is a suitable working electrode for HPLC-ED and provides sufficient sensitivity for determination of tested nitrophenols.
