Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Chromium is the most widely used tanning agent. For the tanner it is easy to use and produces high quality leather. By different retannages and other treatments it is possible to produce quite different leathers, starting from the same chrome tanned stock. Thus chrome tannage is very versatile and shortens the response time of the tanner to the demand for a new leather type. So, from the point of view of a tanner, chromium as a tanning agent has almost only advantages and he will be very reluctant to substitute it by any other tanning agent. Unfortunately, chromium is a heavy metal and thus under environmental scrutiny. Some chromium compounds ar toxic and even carcinogenic. Thus legislation has developed to restrict the discharge of chromium into the waste water and into dolid wastes. Consequently the tanner is obliged to undertake appropriate actions. In the following a short excursion on the legislation on chromium will be given, the sources of discharge from the tannery and measures for restricting it will be discused and then the relevance of chromium as an environmental hazard will be estimated. 2. Legislation on chromium containing. 3. Sources of discharge of chromium into tannery effluents. 4. Measures to reduce the chromium discharge. 5. Relevance of chromium as an environmental hazard.

Environmental aspects of tanning with chromium / J. Gauglhofer in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 70 (Année 1986)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 70 (Année 1986) . - p. 11-13 Titre : Environmental aspects of tanning with chromium Type de document : texte imprimé Auteurs : J.

Tannage Résumé : Methods of preventing the discharge of chromium from tanneries to the environment and their effectiveness and practicability are discussed, viz. Complete uptake and fixation at tanning, direct recycling of spent chrome liquors and precipitation of spent chrome liquors, including reconstitution of new chrome tanning material. However, the chromium cannot be prevented completely from dissipating into the environment. The naturally occuring chromium in soils and the uptake of chromium by plants is discussed. Effects of chromium of chromium on wastewater treatment plants, soils, plants and animals including man are considered, distinguishing between hexavalent and trivalent chromium.
