Abstract

Nile red was examined as a possible fluorescence probe for DDT-type contaminations in aqueous solutions. The effects of such a pesticide (i.e. methoxychlor) on Nile red fluorescence properties was shown to be strong enough for analytical purposes. Several spectral effects were observed: these include a selective complexation reaction, resulting in a new fluorescence peak (at 605nm) and a polarization enhancement of the original Nile red peak (at 663nm). In addition, a linearly dependent blue-shift of the original Nile red fluorescence was obtained. The fluorescence enhancement and intensity of the new complex peak were linearly dependent on pesticide concentration in the μgml^-1 range. The probe showed a certain selectivity to DDT-type pesticides. Copyright (C) 1998 Elsevier Science B.V.
