| 1 | A study on the composition and structure of cyclic sulfoxide derivative palladium(Ⅱ) complex显示文摘The composition and structure of cyclic sulfoxide derivative Pd(Ⅱ) complex were investigated. The coordinated number was studied with slope method. The coordination number is 2 in lower acidity, but it is 3 in higher acidity. Four methods, UV (ultraviolet) spectra, FrIR (Fourier transform infrared) spectra, 1H-NMR (nuclear magnetic resonance)spectra, and 13C-NMR spectra, were used to determine the coordinated atom in complex. Pd is coordinated with O and S atom in S=O group in lower acidity media. The conversion of coordination bond appears with an increasing time. Pd is coordinated with S atom in S=O group in higher acidity media, and inter-ligand-transfer reaction occurs. | WUSongping GUGuobang MENGShuyuan | 2004 | Rare Metals2004，23，4： | 2 |
| 2 | Extraction of palladium(Ⅱ) with OTMSO from acidic media显示文摘The extraction of palladium(Ⅱ) from acidic media with cyclic sulfoxide derivative-α-octyl-tetrahydrothiophene-l-oxide (OTMSO) was investigated. The extraction efficiency of palladination number was studied with slope method. The result indicates that coordination number is 2. FT-IR spectra were used to analyze the structure of complex and coordinated atom in complex. Pd is coordinated with both oxygen and sulfur atom in S=O group in OTMSO .The situation and intensity of peaks contributed by complex prepared from various acidity were different. The recovery of palladium(Ⅱ) with OTMSO from scrap containing palladium was discussed. After silver and bismuth were removed, the feed solution was extracted three times by 40% (volume fraction) OTMSO-kerosene. The loaded organic phase was scrubbed three times,and stripped three times by 2 mol@L-1 NH3·H2O solution.The total recovery of palladium was 99.8%,and the purity of palladium was 99.8%. | WUSongping MENGShuyuan GUGuobang ZHUANGZhiqiang | 2004 | Rare Metals2004，23，2： | 2 |
