Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The influence of chloride and sulfate ions as well as the age of the model test solution of the "tanning liquor" on the effectiveness of the chromium(III) pertraction with the use of a bulk liquid membrane has been investigated. Introducing So2- 4 to the chromium solution causes the creation of stable sulfate complexes that limit the transport capacities of the investigated system with the liquid membrane. the presence of chlorines in the solution does not considerably influence the effectiveness of chromium(III) extraction stripping. As a results restrict the direct application of liquid membranes for the pertraction of chromium from tanning liquors.
