The Tween\u201020 surfactant has been reported for first time to enhance lucigenin chemiluminescence (CL) intensity in the presence of Mn(II) (53%) and maneb and mancozeb (89%). The calibration graphs were linear in the concentration range of 0.001\u20131.5 mg L<jats:sup>\u20131<\/jats:sup> (<jats:italic>R<jats:sup>2<\/jats:sup><\/jats:italic> = 0.9982 (<jats:italic>n<\/jats:italic> = 11) with a limit of detection (<jats:italic>S\/N<\/jats:italic> = 3) of 0.1 \u00b5g L<jats:sup>\u20131<\/jats:sup> for Mn(II) and 0.01\u20133.0 mg L<jats:sup>\u20131<\/jats:sup> [<jats:italic>R<jats:sup>2<\/jats:sup><\/jats:italic> = 0.9989 and <jats:italic>R<jats:sup>2<\/jats:sup><\/jats:italic> = 0.9992 (<jats:italic>n<\/jats:italic> = 6)] with a limit of detection (<jats:italic>S\/N<\/jats:italic> =3) of 1.0 \u00b5g L<jats:sup>\u20131<\/jats:sup> for maneb and mancozeb respectively. Injection throughputs of 90 and 120 h<jats:sup>\u20131<\/jats:sup> for Mn(II) and maneb and mancozeb respectively, and relative standard deviations of 1.0\u20133.4% were obtained in the concentration range studied. The experimental variables, e.g., reagents concentrations, flow rates, sample volume, and photomultiplier tube voltage, were optimized and potential interferences were investigated. The analysis of Mn(II) in river water reference materials (SLRS\u20104 and SLRS\u20105) showed good agreement with the certified values incorporating an on\u2010line 8\u2010hydroxyquinoline chelating column in the manifold for removing interfering metal ions. Recoveries for maneb and mancozeb were in the range of 92 \u00b1 5 to 104 \u00b1 3% and 91 \u00b1 2 to 100 \u00b1 4% (<jats:italic>n =<\/jats:italic> 3) respectively. The effect of 30 other pesticides (fungicides, herbicides and insecticides) was also examined in the lucigenin\u2013Tween\u201020 CL system.
