| 英文摘要 | The borate species in aqueous potassium tetraborate solution were obtained according to the chemical species distribution diagram and the Raman spectrum. X-ray scattering is used to study the solutions with saltwater molar ratios of 1:25, 1:20 and 1:15 at 298 and 323K. The model calculation and model refinement programmes are used to calculate the structure parameters r ij , b ij and n ij . It manifests that the first hydration distance of K+ is approximate to 0.29nm, with an average hydrated number of 8.0. The hydration bond peak is around 0.278nm and the coordination number is from 1.9 to 2.4. Borate anions coordinate with K+ ions in the mono-dentate form, the average distance of KB is 0.38nm. The distance of BH2O in hydrated anion is from 0.37 to 0.38nm with the hydrated number 49. The other interaction such as water shared pair interaction is also discussed. |
