A convenient method for determination of malathion based on the resonance Rayleigh scattering enhancement

Applying resonance Rayleigh scattering and spectrofluorimetric techniques for the selective determination of neomycin sulfate using Congo red as a probe: Applications for wastewater analysis

“…Resonant scattering (RS) is a special kind of elastic scattering with special synchronous fluorescence (λ ex = λ em ). [27] When the wavelength of the scattered peaks of the RRS spectral band is close to the molecular absorption band, resonance occurs, making the intensity of RRS stronger compared with that of a single RS. To date, the RRS method has been widely used for the determination of trace substances, for example, nucleic acids, [28] proteins, [29] inorganic ions, [30,31] organic compounds, [32,33] drugs, [34][35][36] etc.…”
