Abstract

A flow injection system with chemiluminescence detection for the determination of asulam, enhancer of the system luminol–H~2~O~2~–horseradish peroxidase, is proposed. The method shows a moderate selectivity against other pesticides usually present in formulations of herbicides and in water. The procedure was applied to the determination of asulam in tap water samples and a recovery study was carried out in order to validate the method. The obtained results show acceptable recovery values (between 88.3 and 93.9%). The detection limit for asulam was 0.12 ng/mL. The precision of the method expressed as relative standard deviation was 1.55% (n = 8), at the 19 ng/mL level. Copyright © 2009 John Wiley & Sons, Ltd.

## Abstract Abstraction of oxygen from the HRP enhanced chemiluminescence system has no significant effect on the chemiluminescence generated. It is, therefore, proposed that in the peroxidase‐luminol‐perborate system at pH 7.3, chemiluminescence is generated by a direct reaction of diazaquinones w
