The resonance Rayleigh light-scattering (RRLS) signal of a new triazene rea
gent; 1-(o-nitrophenyl)-3-(2-thiazolyl)triazene (o-NPTT), was firstly synth
esized and characterized in this paper at 500-600 nm wavelength range and c
an be enhanced remarkably by Pd2+. According to this phenomenon, a new meth
od 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 c
oncentration 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 sensi
tive, of good selectivity and has been successfully used for the determinat
ion of trace palladium in the slag of fertilizer factories and catalyst sam
