title: Chemiluminometric determination of the pesticide 3-indolyl acetic acid by a flow injection analysis assembly.
abstract: A new method is proposed for the chemiluminescent determination of the pesticide 3-indolyl acetic acid by means of an flow injection analysis system. The chemiluminescence emission is obtained by oxidation of the analyte with Ce (IV) in nitric acid and presence of beta-cyclodextrine. The continuous-flow method allows the determination of 159samplesh(-1) of 3-indolyl acetic acid in an interval of concentrations over the range 0.5-15.0mgl(-1). The limit of detection was 0.1mugl(-1) and the R.S.D. (n, 17) at 2.0mgl(-1) of the pesticide level was 2.7%. The method was applied to water samples.
