| Abstract: | The metal tanning and semi-metal tanning potency of the first row transition metals was studied using hide powder. Transition metals show different levels of synergistic hydrothermal stabilisation in semi-metal tanning. Measurement of hydrothermal stability was carried out regularly in order to monitor the stability and permanence of tanning interactions in metal tanned and semi-metal tanned leathers. The results indicate that the physico-chemical properties of leather can be altered as a result of redox interactions, in which certain transition metals play the role of a catalyst. The extent of metal catalysed oxidative degradation of leather can proceed to the extent of complete destruction of the tanning matrix as well as the collagen itself. A proposed mechanism of metal catalysed autodegradation in semi-vanadium (IV) leather is discussed with regard to experimental results and a review of earlier research on the interaction of vanadium salts with phenolic compounds. |
