| Résumé : |
Basic chromium sulphate and basic aluminium sulphate solutions are the principal tanning liquors in the leather-making industry. In order to improve the qualities of the resultant leather and to do further research on leather-making mechanisms, it is necessary to explore the composition and charges of the above two complex compounds, which also helps research into the theories of complex chemistry. Basic chromium sulphate and basic aluminium sulphate solutions have been separated with columns such as Dowex 50, Zerolite and Sephadex C25. Low pressure ion chromatography (LPIC), was first applied to separate complex compounds and excellent results were obtained. LPIC has such advantages as fast separation, high sensitivity, excellent separation performance and simple operation. |
