Název v původním jazyce

Oxidative and Reductive Detection Modes for Determination of Nitrophenols by High-performance Liquid Chromatography with Amperometric Detection at a Boron Doped Diamond Electrode

Popis výsledku v původním jazyce

High performance liquid chromatography with electrochemical detection using a wall-jet arrangement with a working boron-doped diamond film electrode was used for the determination of 2-nitrophenol, 4-nitrophenol, and 2,4-dinitrophenol using reduction andoxidation modes. The optimal conditions for separation at a C18 reverse phase column (125x4 millimeters, 5 micrometers) and amperometric detection of these nitrophenols were determined. Acetate buffer (0.05mole per liter pH 4.7/methanol 58/42, v/v) waschosen as the mobile phase for cathodic detection at the potential of -1.2 volts. The linear dynamic range was 2x10(-6) to 1x10(-4)mole per liter and the limits of detection were from 0.7 to 1.2 micromole per liter. For anodic detection, the mobile phasewas 0.05mole per liter phosphate buffer pH 6.75/methanol (65/35, v/v) at a detection potential of +1.3 volts. The linear dynamic range was from 2x10(-6) to 1x10(-4)mole per liter with limits of detection from 0.6 to 1.5 micromoles per li
