Abstract
A simple and rapid method determination of phenol is described, using a bro mination reaction and biamperometric detection. The method is based on meas urements of the intensity of current passing through two identical inert el ectrodes giving the concentration of phenol in samples. The sample is injec ted into a stream of carrier and merged with a stream of acidic bromine sol ution which brominates phenol in the reaction coil. A linear relationship b etween peak height and phenol concentration is observed in the range of 0.0 5 to 8 mu g ml(-1) of phenol. The relative standard deviation was 2.8% for analysis of 5 mu gml(-1) phenol and the sampling rate was 70 h(-1).
