  The synthesis and application of 1-(o-nitrophenyl)-3-(2-thiazolyl)triazene for the determination of palladium(II) by the resonance enhanced Rayleigh light-scattering technique

  摘要：

  The resonance Rayleigh light-scattering (RRLS) signal of a new triazene reagent; 1-(o-nitrophenyl)-3-(2-thiazolyl)triazene (o-NPTT), was firstly synthesized and characterized in this paper at 500-600 nm wavelength range and can be enhanced remarkably by Pd2+. According to this phenomenon, a new method was developed for the determination of Pd2+ by the RRLS technique in the presence of Tween-80. The calibration graph showed good linearity over a concentration range of 5.0-700 mu g l(-1) with a detection limit of 1.0 mu g l(-1). There are almost no foreign ions interfered in the determination at a more than fivefold concentration of Pd2+. The method is relatively sensitive, of good selectivity and has been successfully used for the determination of trace palladium in the slag of fertilizer factories and catalyst samples.
