Annotatsiya

The kinetics of the dechroming process of chrome-tanned leather waste (chrome shavings) using citric acid solutions wereinvestigated at different reagent concentrations and temperatures. Based on the obtained kinetic dependencies, the reaction orderwith respect to citric acid, the rate constant, and the activation energy of the process were determined. The dechroming reactionwas found to be characterized by a fractional reaction order (n = 0.44) and a relatively low activation energy (17.6 kJ/mol),indicating that it is a multistep process governed by diffusion and complexation phenomena. A probable mechanism was proposedinvolving the breakdown of Cr(III)–collagen coordination bonds and the formation of soluble chromium(III) citrate complexes.
