| Abstract: | The optimum conditions of solvent flotation of trace noble metals (M: Ru, Rh, Pd and Au) and the color system of M-SnCl2-rhodamine B were studied. The partial least squares-spectrophotometry was used to resolve the overlapping absorption spectra of the associated complexes were determined. The result showed that the system had higher sensitivity and stability. Ru, Rh, Pd and Au in geological samples were determined simultaneously. The relative error was less than 11. 1 %, and standard deviations were 0.0062 to 0.019. |
