摘要：

Studies on the resonance Rayleigh scattering (RRS) spectra of the ion-association complexes of [MoO(SCN)(5)](2-) were carried out with the basic triphenylmethane dye such as crystal violet (CV), ethyl violet (EV), malachite green (MG), brilliant green (BG) and iodine green (IG). The spectral characteristics, the effect factors and the optimum reaction conditions have been investigated. The quantitative relationships of the intensities of RRS to the concentration of molybdenum were established. The new and highly sensitive ways for the determination of molybdenum by RRS have been proposed. The methods can be applied to the determination of trace amounts of molybdenum in steel with satisfactory results.
